Change tracking using Oracle text?

I'm working on a database that does a lot of text handling. My customer is currently using MS Word and they use the track changes feature extensively and would like to keep that function. Has anyone ever used Oracle text to show changes from one paragraph/sentence to another. Can this be done with Oracle Text?
Any help is appreciated.
Tks, Rob

No. Oracle Text does not provide this type of capability.

Using oracle text on a non-materialized view

I'm having trouble tracking down an error when using oracle text on a non-materialized view (indexes are on the referenced columns). My database has a users table and a user history table which saves the old values when a user profile changes. My view performs a "union all" so I can select from both at once.
I would like to use oracle text to perform a "contains" on the view whenever someone signs up to see if any current users or historical entries contain the desired username.
The following works fine:
contains(user_history_view, 'bill')but when I reference anything in the contains clause, i get a "column is not indexed" error:
contains(user_history_view, signup.user_name) --signup.username is 'bill'Here is a stripped-down demonstration (I am using version 10.2.0.4.0)

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

Issues using Oracle Text conditions

Hi all,
I'm facing an issue executing a query on a VIEW using Oracle Text Indexes.
The DB version I'm using is "Enterprise 9.2.0.5".
TEST_VIEW is an sql-view that has a query on several tables where one of them has two Oracle Text indexes, one on field FIELD2 and another on FIELD3
executing this query I get 10 rows:
select *
from TEST_VIEW
where FIELD1 = 1001 -- regular condition
and (contains(FIELD2, 'Blitz') > 0 ) -- Oracle text condition
But if I add another condition on an existent Oracle Text Index, I'll get only 1 row:
select *
from TEST_VIEW
where FIELD1 = 1001
where (contains(FIELD2, 'Blitz') > 0 OR contains(FIELD3, 'Blitz') > 0)
As you can see the third condition was added using a logical OR, so I should get at least 10 rows ...
Can anyone help me ?
ThaNks in advance.
Eduardo.

Eduardo,
Without a full test case, it is hard to see if there is something wrong or not. I did the following, and all worked fine on my 10g instance. I had to assume some things, but I at least think I have the basic gist of your inquiry in this example. Run it/change it to match your situation, and post back when you can.
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)
     OR (CONTAINS(t.titel,:P15_SEARCH_T_O_S)>0 OR

OR (CONTAINS(t.titel,:P15_SEARCH_T_O_S)>0 AND
     CONTAINS (t.oplossing, :P15_SEARCH_T_O_S)>0 AND
     CONTAINS(t.sleutelwoorden, :P15_SEARCH_T_O_S)>0 )
oplossing means solution
sleutelwoorden means keywords
titel means title
Yet this doesn't work yet. It gives an error message:
failed to parse SQL query:
ORA-01719: outer join operator (+) not allowed in operand of OR or IN
I've tried adding the addition in a different place, yet that gives the same error message. I'm not sure now.

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.

Security when using oracle text

Hello,
We would like to use Oracle text functionality on Oracle 10 but the System Admin told us that Oracle is accessing the filesystem with the user account who launched the oracle instance.
He told us that this is a security problem : giving oracle password gives access to the file system.
Is that true and is there a solution to make oracle connect to the filesystem with another linux user account ?
Thanks a lot !

raford wrote:
This only applies when you use the FILE_DATASTORE to index documents on disk, rather than in the file system.
You can restrict access to this feature by only allowing users having a specific role to use it - see
http://download.oracle.com/docs/cd/B28359_01/text.111/b28304/cdatadic.htm#BHCBIFEA
(NB. this is in the 11g documentation - I can't find it in the 10g manual but the functionality is the same).
It's the database process itself which accesses the files, so it will always access them as the owner of the database process, there's no way to change that.What do you mean when you said " FILE_DATASTORE to index documents on disk, rather than in the file system" ?

Using Oracle Text in Oracle XML DB .

Hi all ,
The idea is simple ,i need to index all stored files in Oracle XML DB and the index should stay in Oracle DB . Using some 3 party index software is also possible but you need to write a mapping to move the index file in Oracle DB .
So i thought of using Oracle Text but i am not sure about how to retrieve such a document from Oracle XML DB , let me say over ftp or http ? . And if these documents are password protected -> how can Oracle Text allow this ?

[11gR2 XMLDB Developers Guide -- Full-Text Search over XML Data|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb09sea.htm#i1006756] would be the first place to start.
For document display, there a bunch of potential solutions, you can look at [XML DB Repository|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb03usg.htm#insertedID18], or the Text Application Developers Guide [Presenting Documents in Oracle Text|http://download.oracle.com/docs/cd/B28359_01/text.111/b28303/view.htm#i1006687] .
Password protected documents can't be indexed using the auto_filter.

Oracle Text: How to add/get stopwords list when using Oracle Text world lexer?

I have a use case that we currently use Oracle Text World Lexer to index and search multilingual documents. As we know that World Lexer does the language auto detection. I would like to know the following questions:
Is there anyway I can get the current document's language that Oracle Text detected?
Is there anyway to get the language's stopwords list?
Any thoughts and points will be appreciated.
- Charles

1. If you're using 12c, you can use ctx_doc.policy_languages. (https://docs.oracle.com/database/121/CCREF/cdocpkg011.htm#CCREF24102)
2. If you want multiple stoplists based on each document's language, you have to use the multi-lexer. For world_lexer, there is one stoplist; since the stoplists are somewhat dynamic (you can add but not remove them), the most accurate way to fetch the list is using ctx_report.describe_index or ctx_report.create_index_script and parse the report.

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

Looks like a bad install to me. If this is purely a test database,
I'd suggest reinstalling the whole thing from scratch. If it's not,
then you need to contact Oracle Support to get this resolved.

Using Oracle Text to Data Mine

Can someone provide me with an idea of how to Data Mine with just using Oracle Text and not the data mining option. I need to search a column of customer complaints and then put it in a category based on that. It would be best if the categories were auto generated. It has to be done in PL/SQL.
Thanks,

You cannot have the categories created automatically without data mining. However, if you are willing to create the categories and queries that determine them, then you can do it with just Oracle Text. I posted an example on the 2nd page of the following thread:

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 .
Thanks

APEX app using Oracle Text to index pages that require authorzation

Hi Gurus and APEX Dev team
My team need to develop an APEX App that will index all our documents spread across various servers. Some of the documents require Single sign on access (e.g. KIX.oraclecorp.com) and some require other authorization methods (e.g. Metalink) . The Question is , Is it possible to index the pages that require authorization using Oracle text. If yes How? I have implemented the demo app which can index pages that do not require authorization.
Thanks a million
regards
Bala

Hello,
Unless I misunderstand you, the fact that the pages require authentication doesn't really matter, it is the underlying data you want to index correct? If so then you would index them in exactly the same way that you would index any table data using Oracle Text/interMedia.

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.

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.
