Problems in indexing MS word document. Please help!

Question

Hi
I'm using oracle 8.1.6 on solaris 5.7
I stored a MS word document in a table as a internal blob.
The word document contains one line:
"This is test word document." Then I indexed it with inso_filter preference. I created a log file during indexing. The log file showed thatb there was no document indexed. Here was what I did:
===============================================================
--Create preference
exec CTX_DDL.drop_preference('MY_LEXER');
exec CTX_DDL.create_preference('MY_LEXER','BASIC_LEXER');
exec CTX_DDL.set_attribute('MY_LEXER','MIXED_CASE', 'NO');
exec CTX_DDL.set_attribute('MY_LEXER','INDEX_THEMES','NO');
exec CTX_DDL.set_attribute('MY_LEXER','INDEX_TEXT', 'YES');
exec ctx_ddl.Drop_Preference ('MY_FILTER');
exec ctx_ddl.Create_Preference ('MY_FILTER','INSO_FILTER');
exec ctx_ddl.drop_section_group ('MY_SECTION');
exec ctx_ddl.create_section_group ('MY_SECTION','NULL_SECTION_GROUP');
--Create table
drop table test;
create table test
(id number primary key,
text blob
--Initialize blob column with an empty blob
insert into test (id,text) values (1,empty_blob());
--Create an directory in which a word file (test.doc) exsits
create directory filedir as '/home/mydir';
--Insert the word file
DECLARE
lobd BLOB;
fils BFILE;
BEGIN
fils := BFILENAME('FILEDIR','test.doc');
SELECT text INTO lobd FROM test WHERE id = 1 FOR UPDATE;
dbms_lob.fileopen(fils, dbms_lob.file_readonly);
dbms_lob.loadfromfile(lobd, fils, dbms_lob.getlength(fils));
COMMIT;
dbms_lob.fileclose(fils);
END;
---Start logging
exec ctx_output.start_log('index.log');
---Create index with INSO_FILTER defined in preference
create index test_index on TEST(text) indextype is ctxsys.context
parameters ('lexer MY_LEXER filter MY_FILTER section group MY_SECTION memory 50M');
---Stop loggin
exec ctx_output.end_log;
=============================================================
The indes was created. And I open the index.log file. It is:

I did the query:
select token_text from dr$test_index$i;
no rows returned.
Could anyone tell me why this happened? An advices are appreciated.

Hi, Omar:
I tried use SQL*Loader to load the word document. Part of the loader logging reads as following:
Table TEST:
1 Row successfully loaded.
0 Rows not loaded due to data errors.
0 Rows not loaded because all WHEN clauses were failed.
0 Rows not loaded because all fields were null.
Space allocated for bind array: 6720 bytes(64 rows)
Space allocated for memory besides bind array: 0 bytes
Total logical records skipped: 0
Total logical records read: 1
Total logical records rejected: 0
Total logical records discarded: 0
================================================================
It seems that the file was sucessfully loaded into the database. Then I created index using the procedure I posted on this thread. I checked the table ctx_user_index_errors.
select * from ctx_user_index_errors;
the returns are:
ERR_INDEX_NAME ERR_TIMES
TEST_INDEX 20-FEB-02
ERR_TEXTKEY
AAAGtpABLAAAAAXAAA
ERR_TEXT
----------------------------------------------------------------DRG-11207: user filter command exited with status 137
What does this return tell?
Thanks.
