Structure of Indexes in oracle Text

Hi,
I like to know which Indextyp ist using Oracle Text.
Is it B-Tree Indexes? Or which structure does oracle use to index the dokuments?
I know there are some differences between ctxcat and context.
Can anyone help?
regars,
Arsineh

context is an inverted index structure. ctxcat is based on a b-tree.

How many occurrences of XYZ are there per XML document ?
If there are more than one, then obviously you cannot create such an index on it.
In this case, you'll need an XMLIndex, unstructured or structured, depending on the type of queries you want to run.
If there's only one occurrence, could you post a sample document and your db version?
Thanks.

Does Index in Oracle Text lock local files?

Hi, I am planing to implement content search using file datastore. Let me explain how the whole search going to work, Users are going to upload the file, I am going to store the information about the file like filename, size, keywords, file path etc in Oracle table and I am going to store the original file in a different server. When indexing on filepath, does index lock local files on the Operating system? Does it affect the live data? Please I need answers to this ASAP. Can anyone help?
Thanks,

Hi,
there are differences between the Engine of Text indexing, in 10G it was Verity, in 11G (from version 11.1.0.7) it is the Stellent technology, but I do not hope this is it.
Maybe you could make a dump of the creation of the indexes in both 10g and 11g. This can be done through:
select ctxsys.ctx_report.create_index_script('KSK_FILE_TABLE_CTX1') from dual;
This wil give you a create script with all the parameters. Maybe there is a different in your default settings for text indexes, possible the FILTER.

How to compute a global SCORE over a few oracle text indexed tables?

Dear experts!
I want to search a website with Oracle Text. The website consists of four tables:
- site
- chapter
- text
- binaries
Each table has two or three columns which should be indexed with oracle text. So I have created a MULTI_COLUMN_DATASTORE oracle text index on each table - So I have four indexes on my website.
When I want to search over the website I have to join my 4 tables (4 contain clauses). So how do I get a global SCORE over these 4 contains clauses?
The next question is can I change the weight of my text indexes (useful for the search hit list)? For example the highest weight has the site index, the second highest weight the chapter index and so on?
Thanks
Markus

If it's a simple JOIN, then you could just add the scores for each CONTAINS clause
select score(1)+score(2)+score(3)+score(4)
from table1 t1,table2 t2, table3 t3,table4 t4
where [join conditions]
and contains(t1.col, 'xxx', 1) > 0 or
contains(t2, col, 'xxx', 2) > 0 or
... etc
then to change the weight you just add a multiplying factor.
Can't help thinking it's probably more complex than this, though.

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.

Jap.

Create Oracle Text Index from Java via JDBC

Hi, I have a question relevant to creation of the Text Index in Oracle Text via Java JDBC.
In Java I create client application and I connect to remote Oracle server. (there is Oracle
10g Enterprise Edition 10.2.0.3.0 on Debian Linux OS). In Java I create query:
CREATE INDEX index_name ON source_tab(text) indextype is ctxsys.context
parameters('datastore ctxsys.file_datastore filter ctxsys.null_filter');
and I start it by:
PreparedStatement stmt = db.prepareStatement(query);
ResultSet rs = stmt.executeQuery();
There is problem that Text Index is created empty and when I write out error log then:
DRG-11513: unable to open or write to file "path"
I have on my computer Oracle XE 10g (Windows XP OS) here this application in Java functions
without problems. Without problems it´s with that same query in SQLPlus when I connect at
this remote Oracle server via PuTTY.
Do you know anybody where could be error? Or at worst case where find I more detailed
manual about JDBC Oracle mainly possible errors and problems with compatibility?

Does it work if you don't use "file_datastore"?
Eg. try the following in sqlplus:
create table t (text varchar2(2000));
insert into t values ('hello world');
create index ti on t(text) indextype is ctxsys.context;
select * from t where contains (text, 'hello') > 0;
Then drop the index ti and try the same "create index" through JDBC. Does that work?
If so, then we have some kind of issue with the file_datastore. I assume you are aware that the file will be read by the SERVER, not from the client?
So if your database resides on a Linux box, but you are calling from a Java program on a windows PC, the file names in source_tab(text) must be in Linux format, and must refer to files which are available on the Linux server (and readable by the owner of the Oracle database process).
So /home/me/file.txt might work, but C:\Documents\file.txt will not.

Update Results not Displayed in Oracle Text search with Transactional Index

Hi,
I am working on a solution utilising Oracle Text to give me a probable list of matching records. The problem I have the table I am searching on is prepopulated with seed data and the application we are building is assigning a record and updating the details(columns) against it. This detail is what we are searching on using an Multi Column Datastore index which is refreshed every hr and also has the transactional parameter specified. Unfortunately the Transactional Index does not pick up the updated details, it only seems to work if I insert a new record (which will never happen). This to me sounds like a bug. Any assistance would be greatly appreciated.

Barbara,
I think you may have eluded to my problem. I haven't updated the "dummy" column
The table structure is as follows:
CREATE TABLE WAGN (
     WAGN               VARCHAR2(8) NOT NULL PRIMARY KEY,
     last_name          VARCHAR2(240),
     first_name          VARCHAR2(240),
     middle_name          VARCHAR2(240),
     date_of_birth     DATE,
     gender               VARCHAR2(1),
     status               VARCHAR2(1) NOT NULL,
     signature          RAW(64));
The preference creation is:
BEGIN
     ctx_ddl.create_preference('WAGN_NAME_SRCH', 'MULTI_COLUMN_DATASTORE');
     ctx_ddl.set_attribute('WAGN_NAME_SRCH', 'columns', 'last_name, first_name, middle_name, date_of_birth, gender');
END;
The Index Creation statement is:
CREATE INDEX wagn_srch_idx1 ON WAGN(signature) --Dummy Column
INDEXTYPE IS ctxsys.CONTEXT
PARAMETERS ('DATASTORE WAGN_NAME_SRCH SYNC(EVERY "SYSDATE+60/24/60" PARALLEL 10) TRANSACTIONAL');
And a typical update statement is (contained with PL/SQL):
     UPDATE WAGN
          SET status = x_wagn_assigned_status,
               last_name = p_employee_details.last_name,
               first_name = p_employee_details.first_name,
               middle_name = p_employee_details.middle_name,
               date_of_birth = p_employee_details.date_of_birth,
               gender = p_employee_details.gender
          WHERE WAGN = l_wagn;
So my guess is that because the dummy column (signature) is not updated it is not being reflected in the transactional memory area.

How do I get Oracle Text to index files on a file server?

I am new to Oracle (I'm a MS-SQL DBA looking for a Full-Text Search solution that is better than linking to a MS index server.)
So - Here's the objective:
I have Oracle Server(Express) installed on a Windows server.
I would like for Oracle to build a Full-Text Catalog of the files on a separate file server based on file paths in a table in the database.
(No desire to store terabytes of images and documents inside the database)
I can get Oracle text up and running, using the URL_Datastore:
CREATE TABLE files (id NUMBER PRIMARY KEY, issue_id NUMBER, path VARCHAR(255) UNIQUE, ot_format VARCHAR(6), ot_version VARCHAR(10));
The Compaq server is a remote windows server on my local workgroup, so the fully qualified path is just "compaq" and the URL is valid:
INSERT INTO files VALUES (9,9,'file://Compaq/FTQ/00000003.pdf',NULL,NULL);
INSERT INTO files VALUES (13,13,'file://Compaq/FTQ/01.txt',NULL,NULL);
CREATE INDEX file_index ON files(path) INDEXTYPE IS ctxsys.context
PARAMETERS ('datastore ctxsys.URL_DATASTORE format column ot_format');
but when I enter:
Select * from CTX_User_Index_errors, I see the following errors:
DRG-11609: URL store: unable to open local file specified by file://Compaq/FTQ/00000003.pdf
DRG-11609: URL store: unable to open local file specified by file://Compaq/FTQ/01.txt
Did I miss something?
Do I need to install anything on the file server?
I would like to convince my company that Oracle can be much quicker than Microsoft's Indexing Service because it can avoid joining two large result sets (one result set from Full_text (indexing service) and one for specific data contained in fields in the MS-SQL database.) Full Text Searches commonly take 40 - 60 seconds where there are 1.5 million multi-page PDF files for a particular set that I sample search on. Without this massive join, I believe I can get the search to run in under 10 seconds.

Thank you!
File_Datastore worked fine.
I was staying away from File_Datastore because the information I gathered from googling suggested that file_datastore would only work locally.
Now I just have to get Oracle to pull data out of tables in a MS-SQL database on the local network (don't have a clue yet), and then have it index compiled file paths.
Then MS-SQL can query Oracle with index and full-text criteria and Oracle can send back a result set
It may sound like a bad way of performing Full-Text Queries, but anything will be better than the way things are currently running. We are currently performing Full Text Searches on a table that is rebuilt nightly, so the table containing millions of file paths is not live..
It would be so much better if we just migrated to Oracle, but we currently do not have the resources.

Error while running the Oracle Text optimize index procedure (even as a dba user too)

Hi Experts,
I am on Oracle on 11.2.0.2 on Linux. I have implemented Oracle Text. My Oracle Text indexes are fragmented but I am getting an error while running the optimize_index error. Following is the error:
begin
ctx_ddl.optimize_index(idx_name=>'ACCESS_T1',optlevel=>'FULL');
end;
ERROR at line 1:
ORA-20000: Oracle Text error:
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.CTX_DDL", line 941
ORA-06512: at line 1
Now I tried then to run this as DBA user too and it failed the same way!
begin
ctx_ddl.optimize_index(idx_name=>'BVSCH1.ACCESS_T1',optlevel=>'FULL');
end;
ERROR at line 1:
ORA-20000: Oracle Text error:
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.CTX_DDL", line 941
ORA-06512: at line 1
Now CTXAPP role is granted to my schema and still I am getting this error. I will be thankful for the suggestions.
Also one other important observation: We have this issue ONLY in one database and in the other two databases, I don't see any problem at all.
I am unable to figure out what the issue is with this one database!
Thanks,
OrauserN

How about check the following?
Bug 10626728 - CTX_DDL.optimize_index "full" fails with an empty ORA-20000 since 11.2.0.2 upgrade (DOCID 10626728.8)

Suggestion: Oracle text CONTEXT index on one or more columns ?

Hi,
I'm implementing Oracle text using CONTEXT ..... and would like to ask you for performance suggestion ...
I have a table of Articles .... with columns .. TITLE, SUBTITLE , BODY ...
Now is it better from performance point of view to move all three columns into one dummy column ... with name like FULLTEXT ... and put index on this single column,
and then use CONTAINS(FULLTEXT,'...')>0
Or is it almost the same for oracle if i put indexes on all three columns and then call:
CONTAINS(TITLE,'...')>0 OR CONTAINS(SUBTITLE,'...')>0 OR CONTAINS(BODY,'...')>0
I actually don't care if the result is a match in TITLE OR SUBTITLE OR BODY ....
So if i move into some FULLTEXT column, then i have duplicate data in a article row ... but if i create indexes for each column, than oracle has 2x more to index,optimize and search ... am I wright ?
Table has 1.8mil records ...
Thank you.
Kris

Another option would be something like this.

Were i you, i would try out those 3 approaches and see which meet your performance requirements and weigh that with the ease of implementation and administration.

Index creation in Oracle Text ???

Hi,
I have never used oracle text before.
The background info is got corruption errors on database alert log, identified it is an oracle9.2.0.5 bug in aix 5.2, need to apply 9.2.0.6 patchset. Temporary solution provided by oracle support was to drop and recreate an index.
My approach was to identify the index name, associated column, reverse engineer the object ddl, drop the index and re-create the index. Should have been straight forward. The difference is the column is of BLOB datatype. My index script failed with ORA-02327. I get errors on alert log saying missing index.
Don't know how to re-create the index on BLOB column in a table.
Any help, much appreciated.
Thanks
Murali

Hi,
For your recreation, check out CTX_REPORT.CREATE_INDEX_SCRIPT. It will generate all of the ddl that you need.
Thanks,
Ron

Index rules in oracle text and query using matches

Dear All,
I would like to ask about rules and matches function in oracle text.
I followed an example in oracle text application developer's guide.
I have a rule table like this :
1 oracle
2 larry or ellison
3 oracle and text
4 market share
then, I create an index to that table. This is needed for calling matches function. Here is the syntax :
create index queryx on queries(query_string)
indextype is ctxsys.ctxrule;
then, I noticed that the result on DR$QUERYX$I table as follows :
LARRY 0 2 2 1 (BLOB)
MARKET 0 4 4 1 (BLOB) {MARKET} {SHARE}
ORACLE 0 1 1 1 (BLOB)
ORACLE 0 3 3 1 (BLOB) {TEXT}
ELLISON 0 2 2 1 (BLOB)
What I want to ask is why doesn't the words 'share' and 'text' appear in the DR$QUERYX$ table?
When we use matches function, it then search on the index result and consequently it wion't find the 'share' word. so when for example I do query like this :
select query_id from queries where matches(query_string,' It only share ten percent of all products sold')>0
it will give 0 result since the no word in ' It only share ten percent of all products sold' was in index table. But actually it could possibly be categorized as the 4 category which rules is 'market share'
I tried this in a larger set of data and get same result.
Here is my generated rules from my document collection :
1 {REQUIREMENTS} & {ELICITATION}
1 {REQUIREMENTS} ~ {ELICITATION} & {ACTOR}
1 {REQUIREMENTS} ~ {ELICITATION} ~ {ACTOR} & {FURPS}

Thank you very much.

Hm, I see. It do make sense. so nice to know.
But then in the second example I gift where I used larger table, as shown below :
Here is my generated rules from my document collection :

2 {DESIGN} ~ {REPRESENTATION} ~ {MAY}
3 {PM} & {TESTING} & {ATTRIBUTI}
As far as I know, the sign ' ~ ' means 'OR' and '&' means 'and' . So based on the 4th line in my table :
1 {REQUIREMENTS} ~ {ELICITATION} ~ {ACTOR} ~ {FURPS} ~ {OUTLINE}
it can be concluded that if any of the words stated there been queried, so the category '1' will appear as a result. But then before we can use 'matches' to query it, we need ti create index for the rules table . I did it and the result were :

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.
