I am using ORACLE 10g Rel 2 Express Edition i.e. Oracle XE.

I have a table structure like
Table = docs
doc_id NUMBER
document BLOB

We are using this table to store MULTILINGUAL PDF, MS-Excel, MS-Word documents.
I created an index as shown below using Oracle Text to search documents as per data in the documents.
Index:
CTX_DDL.CREATE_PREFERENCE('doc_search_lexer', 'WORLD_LEXER');

CREATE INDEX doc_search_binary_idx on docs(document)
INDEXTYPE is CTXSYS.CONTEXT
PARAMETERS ('LEXER doc_search_lexer
STOPLIST CTXSYS.EMPTY_STOPLIST');

I used the following two procedures to optimize & synchronize the Index:
CTX_DDL.SYNC_INDEX('doc_search_binary_idx');
CTX_DDL.OPTIMIZE_INDEX('doc_search_binary_idx', 'FULL');

The SELECT query that I use is:
SELECT * from docs
WHERE CONTAINS(document, 'search string') > 0;

To test the Index, I uploaded two exactly same documents in MS-WORD & PDF format, which were in Hindi (Devnagari script) & executed the optimize & synchronize procedures & then executed the SELECT SQL. The result set lists only the matching MS-word documents, PDF documents (which are exactly same w.r.t. data inj document) are not returned. The PDF documents attributes under "File --> Document Properties --> Font" are OK w.r.t. Oracle Text documentation.
I referred the table "DR$DOC_SEARCH_BINARY_IDX$I", the tokens are not being generated for PDF documents.
What is the way out to Index documents (PDF, MS-Excel, MS-Word) (MULTILINGUAL)???

You might try adding auto_filter to your index parameters.

I have already tried using "AUTO_FILTER" in my filter preference, but I am not getting the correct data.

Maybe this?
GRANT RESOURCE, CONNECT, CTXAPP TO MYUSER;

GRANT EXECUTE ON CTXSYS.CTX_CLS TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_DDL TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_DOC TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_OUTPUT TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_QUERY TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_REPORT TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_THES TO myuser;
GRANT EXECUTE ON CTXSYS.CTX_ULEXER TO myuser;

Never grant predefined roles like CONNECT and RESOURCE, and above all NEVER grant RESOURCE.
Always create your own.
