Hi All,

I have a test table with three columns (id,name,doc) where doc column is of blob type.

I am mentioning the step I have followed to create index and then search the document containing the keyword using the CONTAIN keyword.

I am able to find the documents in English Language but not able to find documents in other langauges.

Please help me out.

Are you expecting oracle text to translate the documents into english?

No I just want to display the record in which the search sting exists.

Look at this:

SELECT SCORE(1) score, id, name
FROM   test
WHERE  CONTAINS(doc, '箭头显示在两个方向 ', 1) > 0
ORDER BY SCORE(1) DESC;


no rows selected.

Thanks

According to what you posted, you have not synchronized the index after loading the additional files. So, even though you have 8 rows in the table, only the first 3 that you loaded before you created the index have been indexed, so you will not be able to search anything in the other 5. After loading, you need to synchronize.

Hello Mam,

I used the below mentioned command to synchronize the Index:

begin
ctx_ddl.sync_index('SAMPLE_DOC_IDX');
END;


SELECT SCORE(1) score, id, name
FROM   test
WHERE  CONTAINS(doc, '箭头显示在两个方向', 1) > 0
ORDER BY SCORE(1) DESC;


Still no rows selected.

doesnot seems helping out.

Deepak

I have found some procedure to synchronyze the context index and after making the changes accordingly still "no rows returned"

Below is the procedure created:

CREATE OR REPLACE  
Procedure sync_ctx_indexes 
IS  
CURSOR sql1 is select distinct(pnd_index_owner||'.'||pnd_index_name) as index_name from CTXSYS.ctx_pending; 
BEGIN  
FOR SAMPLE IN sql1 LOOP
ctx_ddl.sync_index(SAMPLE.SAMPLE_DOC_IDX); 
END LOOP; 
END; 



Again when I executed the same sql statement for the search , got the same result:

SELECT SCORE(1) score, id, name
FROM   test
WHERE  CONTAINS(doc, 'Datenbankebene ', 1) > 0
ORDER BY SCORE(1) DESC;


Help me out plsss.

Thanks
Deepak

I have also checked the ctx_pending view but there are no indexes pending for the sample user.

Try testing just a simple example first, inserting test data directly through SQL, without loading a file, inserting before you index, checking that the data is loaded, checking that the data is indexed, then testing the queries, as shown below. I have provided the test script and a run of it separately. It does not display properly on my system due to character set issues, but it still indexes and finds the data. Please post the results from your system in the same manner. If that does not work, then we need to figure out why. If it does work, then you can add one more thing at a time to it until it does not work, which should show where the problem is. You should re-run the full script and check to make sure that the data is loaded and check to make sure that the data is indexed with each test after adding something. Frequently problems are that the data was not properly loaded or not done indexing or synchronizing.

create table test
  (id    number primary key,
   name  varchar2(2000),
   doc   blob)
/
-- insert data before indexing:
insert into test (id, name, doc)
values (1, 'test1', utl_raw.cast_to_raw ('Tomcat'))
/
insert into test (id, name, doc)
values (2, 'test2', utl_raw.cast_to_raw ('Datenbankebene'))
/
insert into test (id, name, doc)

Did you insert some data that was just displayed as a string of question marks or did you actually insert a string of questions marks? If you inserted a string of question marks, then they would correctly not be indexed, and a query with just question marks in the search string would correctly cause an error. It looks like that is what happened. When I ran my test case, I put the test case in a sql file, then ran that file, spooling the results. Because of the special characters, I saved the sql file that I ran as utf-8 and included a blank line at the top of the file.

Start by checking that the documents are loaded properly:

select id, name, length (doc) from test;

Then check that they are indexed properly:

select token_text from dr$sample_doc_idx$i;

Your query below does not match the output. Where is the length (doc)? Do you see the value that you are searching for in the token_text of the other query or something similar due to display issues? Try loading just one simple document, perhaps with only one word in the foreign language that is a problem, so that it is easier to test.

SQL> select id, name, length (doc) from test;

Check this out Mam..

All this data is the result of the query to check tokens.

but when I rty to run the serach query for one of the string "V+RIFIEZ" still there is "no row returned".

SQL> ed
Wrote file afiedt.buf

  1  select score (1) score, id, name
  2    from   test
  3    where  contains (doc, 'V+RIFIEZ', 1) > 0
  4*   order  by score (1) desc
SQL> /

no rows selected


More over one of the character of the string changed automatically. When I tried to run the query on the SQL developer the strinf was exact same as it was in the token but still there was no row returned.

Below is the query which I ran in SQL Developer..
select score (1) score, id, name
  from   test
  where  contains (doc, 'V╔RIFIEZ', 1) > 0
  order  by score (1) desc


Now what could be the problem Mam?

Thanks
Deepak

With the lexer that you posted, it would not index the + symbol, so I think you are doing something different than what you have posted. You need to keep the test case as simple as possible and be consistent.

Also, when you run your test queries, make sure that you are running them using the same method that worked previously, storing the query to a sql file, with a blank line at the top, saved as utf-8 and spooling the result when you run it.

Also, make sure that you search for the same string that was entered, as it was entered in the document, not how it is displayed as token_text due to distortion when the operating system character set does not match.
