Using Oracle Text for searching with UCM 10g

I am using Oracle text with UCM 10gR3 and Site Studio 10gR4 and I am trying to sort the search results by relevancy and to also include a snippet of the retrieved document. I have the fields that the SS_GET_SEARCH_RESULTS service returns but the relevancy score is always equals 5 and the snippet contains characters such as < idcnull, /p, etc., which you can see are XML/HTML/UCM tags but which result sin even more strangeness in the snippet if I try to remove them programmatically.
I have read the Oracle Text documentation and there appear to be ways you can configure Oracle Text but I am not clear at all on what I can do from UCM. It looks like the configuration is either done in database tables or in the query itself, neither of which are readily configurable to me.
Is anyone experienced in this or know of any documentation this might help?
Bill

Hi
If I remember correctly then this issue was seen with an older version of OTS component and Core Update patch / bundle . Upgrade the UCM instance with the latest CS10gr35 update bundle patchset 6907073 and also upgrade OTS component from the same patchset .
Let me know how it goes after this .

Using Oracle Text to search through WORD, EXCEL and PDF documents

Hello again,
What I would like to know is if I have a WORD or PDF document stored in a table. Is it possible to use Oracle Text to search through the actual WORD or PDF document?
Thanks
Doug

Yes you can do context sensitive searches on both PDF and Word docs. With the PDF you need to make sure they are text and not images. Some scanners will create PDFs that are nothing more than images of document.
Below is code sample that I made some time back to demonstrate the searching capabilities of Oracle Text. Note that the example makes use of the inso_filter that is no longer shipped with Oracle begging with Patch set 10.1.0.4. See metalink note 298017.1 for the changes. See the following link for more information on developing with Oracle Text.

Using Oracle Text for Text Mining

Hi all !
I have 30000 text documents stored in a table and I want to construct a "dictionnary" that contains all the terms include in those documents. I will use this dictionnary to classify my documents with the text mining solutions of Oracle.
I created an index with a multi datastore, specific lexer, stoplist and wordlist and it creates well my dictionnary. The problem is that I would like to add some other tokens containing more than a word. I wonder how to use the index created : I tried to work on the table $I created for the index but it's not really successful. So I thought about 2 solutions :
- work on the index with insert, delete and synchronise operations
- find a way to insert the additionnal tokens (which corresponds to pattern) during the indexing operation
Can you help me ?

Hi,
Check out a thesaurus (enter your phrases here) and see if it will do what you need:
http://download-west.oracle.com/docs/cd/B19306_01/text.102/b14217/cthes.htm#i1006324
Don't modify the $I table as a general rule (or any system-generated table).

Oracle text for varchar2

Hi ...
can i use oracle Text for searching in varchar2 field ....
IF yes , plz give me the details ....
Thanks ....

SELECT OD OID, TAB Layer, COLUM Field, TEX Result,
score(22) Score FROM VIEW_MASTER
WHERE CONTAINS ( TEXT_VALUE, SEARCH_TERMS, 22 ) > 0
ORDER BY Score;
The search_terms are an inbound parameter. Not sure
what the 22 does, i think its just an alias name. I
don't know what the score coming back means.
Sometimes I get 16, sometimes 12, sometimes 7.
I could use some help on this myself.Yes, 22 is just an alias. You can use any number here since it is just a label which is used to correlate the CONTAINS function with its corresponding SCORE function.
The details of how the score is computed are available in the Oracle Text Reference book, Appendix "F The Oracle Text Scoring Algorithm".

Oracle Developer 6 applications with database 10g

Hello,
My all applications are developed and running in Oracle Developer 6 with database 9i. But now i want to use
database 10g with these Oracle Developer 6 build applications.
Already compiled files (with dev 6 and DB 9i) are runing with database 10g quite nicely,but when i try to
recomplie the source files of these applications with 10g database i got the fowlloing error.
ORA-00600: internal error code, arguments: [17069], [45468896], [], [], [], [], [], []
After it i open these Oracle Developer 6 applications source files with Oracle Developer 6i and use 10g database,
compile and run very easly.
I think it is old version problem .But my development team dont want update all applications to new version (6i or other) yet.
Is there any solution to use Oracle Developer 6 applications with database 10g ?
Thanx.

The general rule is "Ora-00600s (and 7445s, 3113s) are to be reported to Support". Look in Metalink to see whether any one else has reported it, based on the first argument. If so, there may be a workaround or a patch.
Since you are asking this generically without database version, patch level or operating system, I assume you are using the unsupported free download and do not have access to Metalink. In that context
1) What is the problem:
The problem is your request (QSL, PL/SQL, Java) is hitting a bug or abusing a part of the Oracle software in an unexpected way. ORA-00600 is simply one of the 'unexpected and unhandled exceptions'.
2) Required action:
Since it is unexpected and unhandled, there are several ways to proceed:
- Search the net for the first argument (ktspgetmyb-1) to see whether someone has a workaround
- Reproduce and Simplify your offending code until you find your own workaround.
Often this happens with some sql statement

Problem with blob column index created using Oracle Text.

Hi,
I'm running Oracle Database 10g 10.2.0.1.0 standard edition one, on windows server 2003 R2 x64.
I have a table with a blob column which contains pdf document.
Then, I create an index using the following script so that I can do fulltext search using Oracle Text.
CREATE INDEX DMCS.T_DMCS_FILE_DF_FILE_IDX ON DMCS.T_DMCS_FILE
(DF_FILE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('DATASTORE CTXSYS.DEFAULT_DATASTORE');
However, the index is not searchable and I check the following tables created by database for my index and found them to be empty as well !!
DR$T_DMCS_FILE_DF_FILE_IDX$I
DR$T_DMCS_FILE_DF_FILE_IDX$K
DR$T_DMCS_FILE_DF_FILE_IDX$N
DR$T_DMCS_FILE_DF_FILE_IDX$R
I wonder what's wrong with it.
My user has been granted the ctx_app role and I have other tables that store plain text which I use Oracle Text are fine. I even output the blob column and save as pdf file and they are fine.
However the database seems like not indexing my blob column although the index can be created without error.
Please advise.
Really appreciate anyone who can help.
Thank you.

The situation is I have already loaded a few pdf document into the table's blob column.
After I create the Oracle text index on this blob column, I find the system generated index tables listed in my earlier posting are empty, except for the 4th table.
Normally we'll see words inside the table where those are the words indexed by oracle text on my document.
As a result, no matter how i search for the index using select statement with contains operator, it will not give me any result.
I feel weird why the blob is not indexed. The content of the blob are actually valid because I tested this by export the content back to pdf and I can still view and search within the pdf.
Regards,
Jap.

Searching using Oracle Text instead of LIKE '%'

Hello all,
I hope you help me in this:
I have a table looks like this
create table subscribers (
id numer(10),
first_name varchar2(30),
father_name varchar2(30),
grandfather_name varchar2(30),
last_name varchar2(30))
The application is built using Oracle Forms. Many times, the end users are not so sure of the spelling of the name, therefore they use the "%" wildcard with name fields. This will be reflected to the queries the application will send them to the Oracle Server.
We have the following queries
1) select *
from subscribers
where last_name like '%family_name%';
2) select *
from subscribers
where last_name like 'family_name%';
3) select *
from subscribers
where last_name like '%family_name%' and first_name like '%first_name%';
4) select *
from subscribers
where last_name like 'family_name%' and first_name like 'first_name%';
As well as searching on the father_name and grandfather_name fields. But most of the search are on the first_name and the last_name.
These queries are killing the server since we have millions of records. BTree indexes will not help here because of the LIKE and the "%"
I am thinking to use Oracle Text here, but I am not sure whether I have to go for a CONTEXT index on each individual column, or I can use the MULTI_COLUMN_DATASTORE indexing.
Any idea will be appreciated

The ctxcat index and catsearch operator are generally intended for usage with one text column and one or more columns of structured data. You would have to pick just one of your columns as the text column and the others as structured columns. I would be more inclined to use the multi_column_datastore with a context index and contains operator, so that you can search all of your columns as text columns.

You could use an Oracle Text context index with a wordlist to speed up substring searches and return all rows that match any of your criteria, combined with a case statement to provide a ranking that can be ordered by within an inner query, then use rownum to limit the rows in an outer query. You could also use the first_rows(n) hint to speed up the return of limited rows. Please see the demonstration below. If you decide to use Oracle Text, you may want to ask further questions in the Oracle Text sub-forum on this forum or space or whatever they call it now.

Patches 7446163 y 6851110 in order to use Oracle Text from UCM

Hello, we have Oracle Enterprise Edition 11.2.0.1 on AIX 6.1.0.0 (64 bits). The client want to use Oracle Text from Universal Content Management, he told me about install the patches 7446163 y 6851110 in order to enable Oracle Text from UCM. I reviewed in Metalink but the readme said that those patches are for Oracle 11.1.0.7. That version (11.2.0.1) include already those patches or those are necessary for we can use the funcionality of Oracle Text from Universal Content Management? I reviewed the components installed on database and the Oracle Text is installed and active.
Thanks for your help.
Sincerely,
Ruben Nieto
DBA

Hi
Oracle DB usually would be installed with Oracle Text enabled (the db side) . To use the features for this we need to have OracleText component enabled on UCM which as you mentioned is already installed and enabled on the ucm server .
If both the above conditions are already met then you would not need to install any further patches.
Let me know if it is fine on db and ucm .
Verify that Oracle Text is enabled on db by executing the following query :
select comp_name, status from dba_registry;
It should return the the following result : Oracle Text VALID
To verify if the component for UCM is installed then you would need to check Administration - Configuration for <instance name> - Enabled Components
Thanks

Oracle iRecruitment: Keyword Search within Resumes using Oracle Text

Dear All,
As per my understanding (and Note: 247064.1) simple Keyword searches can be performed in iRecruitment if oracle Text is installed. However searching for Keywords within resumes is not possible using Oracle Text and is possible ONLY if Resume Parsing is enabled via a third party (non-oracle) service provider.
Can you please let me know if my understanding is correct and if not provide further inputs on this.
Thanks,
Subrat

Got this confirmation from Oracle via SR:
Resume searching is independent of resume parsing and not required to search resumes.
Oracle Text is the text engine that allows you to search documents using content-based queries. Oracle Text allows you to upload documents, search documents, parse resumes, etc.
Hence to conclude - Installation of Oracle Text will allow Keyword Searches on resumes.
Thanks,
Subrat

Configuring Oracle Text for 10g

Hello,
Sorry, it this sounds like such a newbie question, but is there is a simple guide to the basic configuration and setup of Oracle Text for 10g?
Thank you for your help.

Hi,
Check out note 280713.1. You can verify your install and install manually if necessary.
If you haven't done anything with the db (created schemas/objects) it might actually be easiest to simply delete the db and create a new one. Just make sure when you do that you select 'custom' from the list of templates and then choose Oracle Text as one of the options.
Thanks,
Ron

Using oracle text in apex report search

I am trying to use oracle text in apex, integrating it in an existing application. The idea is that it will allow to do a search in bigger textfields. Thats how I want it to get to work. In one of the oracle packaged applications oracle text is used as well, so I will have a look to that as well. I've addapted this search. I've added
AND t. contains(oplossing, :P15_OPLOSSING)
AND t.contains(sleutelwoorden, :P15_SLEUTELWOORDEN)
That didn't work, so I changed those two to:
AND t.oplossing = (t.contains(oplossing, :P15_OPLOSSING)>0)
AND t.sleutelwoorden = (t.contains(sleutelwoorden, :P15_SLEUTELWOORDEN)>0)
which didn't work either, which I expected to be the case. Clearly I'm not doing it correctly, I intend to look it up tonight in the packaged applications as I do want to findt it myself to.
But does anyone can give a hint, on what I am doing wrong ?

I have worked it further out now, and looked at the search of the packaged application. It turned out to be a pl/sql block . I used what I found in there to adapt the previous search. I added the following:

OR (CONTAINS(t.sleutelwoorden, :P15_SLEUTELWOORDEN)>0)

Yet this doesn't work yet. It gives an error message:

I've tried adding the addition in a different place, yet that gives the same error message. I'm not sure now.

Document management system using oracle text

i plan to create document management system using oracle text with following features
1) document comparision
2) document search
and more...
can oracle text be used to display documents of various formats by converting them to HTML. and can search keywords be highlighted in the document.
please help!

Have you ever considered doing this in Oracle Application Express (free on top of the Oracle database)? How about something like:
http://download-west.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm
Index the files using the CONTEXT index, and perhaps the docs' meta with it using the Oracle Text MULTI_COLUMN_DATASTORE, and then when you write your query for a report on the documents include a search string.
I've created a number of APEX-based document management systems and it is quite easy once you get the hang of using this environment. I suggest looking at some of the tutorials/how-to documents and you'll be on your way quickly.
Start with the upload application. Once you can get your documents in, create a report that shows everything except the document. Verify all of this works correctly.
Add some "items" to the page for the report, and include them as bind variables in the where clause.
After that, add your Oracle Text index to the database, and toss in a "text-field" item to the APEX page. Modify your report query, adding the CONTAINS clause, and use the newly created item as a bind variable. There's your keyword search.
Linking to Oracle Apps is done through API's and may be over database links.
Hope it helps. Though not a step-by-step how to document, this should point you in the right direction. Get familiar with APEX as that covers most of what you described.

NEAR operator alternative when not using. oracle Text ?

hi,
I'm working on a project where i would need a Oracle Text 'NEAR like' operator ...
here is my scenario ...
in db we have Customers ... and every customer has some criterias like different search words( names, towns,cars,etc...) so for every customer i can create an SQL query out of criterias . ....
now .... we can have a criteria like. ...... WHERE fulltext like 'john%'. or even distance search line NEAR inside CONTAINS. ... but then the Oracle text index is needed .....
the only tAble on which Text index is created is our storage table that holds more then 4mil records and growing...
my question is ... is there any way to have a query that would do the same thing as NEAR but without Text index ?
here is how I start ....
I get full newspaper article text from our OCR library ......
then i need to check customer's criterias against this text to see which article is for which customer and then bind the article to the customer
I could do it without Oracle using RegEx , but criterias can get really complicated ... like customer wants only specific MEDIA, or specific category , type , only articles that are from medias that are from specific country etc ... and many more different criterias ... and all this can be wrapped inside brackets with ANDs, ORs, NOT. ....
So the only way to do it is to put it in Oracle and execute the correct query and let Oracle decide if the result is true or false .... but due to NEAR operator I need Oracle text ...
So if I decide to first insert article into our storage table which has Oracle text index to be able to do the correct search .... how fast will this be ????
will the the search become slower when there are 6mil records ? I know I can use FILTER BY to help Text index to do a better and quicker seach ... and how to optimize index ....but still
I'm always asking my self..... why insert the article in a table where there are already 6mil articles and execute query when I only need to check data on one single article and. i already know this article ...
I see two solutions :
- if there is alternative for NEAR without using Oracle text index then i would insert data into temporary table and execute query on this table..... table would always contain only this one article. maybe one option would be to have one 'temp' table with Oracle text index in which i insert this one article and with help of Oracle text based on this one article do the search , and then maybe on a daily basis clear index ..... or when the article is removed from the table ... but this would mean having two Orcle text indexes, cause we already have Oracle text index on our storage table anyway....
- another is to use Oracle text index and insert it into our storage table and hope for the best quick results ....
Maybe I'm exaggerating and query like WHERE id=1234 and CONTAINS(...). will execute faster then I think
If anyone would have any other suggestion I will be happy to try it ..
thanks,
Kris

Hi,
this is to my knowledge not possible. It is hard for Oracle to do, think about a table with many rows, every row with that column must be checked. So I think only a single varchar2 is possible. Maybe for you will a function work. It is possible to give a function as second parameter.
function return_signup
return varchar2
is
l_signup_name signup.signup_name%type;
begin
select signup_name
into l_signup_name
from signup
where signup_id = 1
and rownum = 1
return l_signup_name;
exception
when no_data_found
then
l_signup_name := 'abracadabra'; -- hope does not exist
return l_signup_name;
end;Now you can use above function in the contains.
select * from user_history_view users --, signup new_user
--where new_user.signup_id = 1
where contains(users.user_name, return_signup)>0;I didn't test the code! Maybe you have to adjust the function for your needs. But it is a idea how this can be done.
Otherwise you must make the check by normaly check the columns by simple using a join:
select * from user_history_view users, signup new_user
where new_user.signup_id = 1
and users.user_name = new_user.signup_name;Herald ten Dam

SMB Server using Oracle Text Index

Hi folks,
I am looking into IFS and can't find any info
on whether IFS is able to use the Oracle Text
indexing, when accessed through SMB (directory mount).
If I search for a file containing a given string
is that search executed within IFS and only the
resultset returned to the client, or is every
file read from IFS delivered to the client,
searched there and then thrown away if it doesn't
contain the string (rendering the Text Index useless)?
Does anybody have background info / experience with this?
Regards
Jan-Peter

Jan-Peter To answer your question, it would help to have a little more context (pardon the pun). Are you trying to (1) understand how the 9iFS Windows UI uses Oracle Text, or (2) are you trying to write a client application that somehow uses the Text index on 9iFS content?
