ORA-29902: error in executing ODCIIndexStart() routine

Question

Hi,
I have a problem with my text mining application.
when I start the classification procedure I get the following errors
Error executing statement: ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: Oracle Text error:
DRG-50857: oracle error in drcs_query
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at "CTXSYS.DRVODM", line 676
ORA-01426: numeric overflow
ORA-06512: at line 1
After closing and restarting the SQL Navigator, most times it works again, but not every time.
Here is the procedure I use:
PROCEDURE sp_classify
IS
vc2_sqlcommand VARCHAR2(1000);
guete DBMS_SQL.number_table;
branche DBMS_SQL.varchar2_table;
BEGIN
vc2_sqlcommand := 'ALTER TABLE ergebnisse MOVE TABLESPACE xxx;
execute IMMEDIATE vc2_sqlcommand;
n_matchscore := 20;
INSERT INTO ergebnisse
SELECT rt.cat_id, pt.produktions_id, match_score(1) AS MatchScore
FROM produktionsdaten pt, trainingsregeln rt
WHERE matches ( rt.rule, pt.geschaeftsgegenstand, 1) > n_matchscore;
COMMIT;
vc2_sqlcommand :=
'CREATE INDEX I_ERG_PRODID ON ERGEBNISSE ' ||
'( PRODUKTIONS_ID ASC ) ' ||
'TABLESPACE XXX' ||
'STORAGE ( INITIAL 64K ' ||
'NEXT 64K ' ||
'PCTINCREASE 0 ' ||
execute IMMEDIATE vc2_sqlcommand;
Please help me

I agree with Omar, However if you want to search using special character, you may want to look into the following example. I am not saying this may be a solution for you, however this may give you a start on how to deal with special character in you search.
In our enviroment we have "N" number of Science & Pharmacy & Chemical clients. They need the ability to search using special character for that we have done the following..
begin
select user into v_username from dual;
ctx_ddl.create_preference('orc_CTX_WLPREF', 'BASIC_WORDLIST');
ctx_ddl.set_attribute('orc_CTX_WLPREF','SUBSTRING_INDEX','TRUE');
ctx_ddl.set_attribute('orc_CTX_WLPREF','WILDCARD_MAXTERMS','2559');
ctx_ddl.Create_Preference('orc_LEXER','BASIC_LEXER');
ctx_ddl.Set_Attribute('orc_LEXER', 'index_themes', 'FALSE');
ctx_ddl.set_attribute('orc_LEXER','printjoins','0123456789%,./?;:<>[]{}\|+=-_()*&^$#@!''"%');
end;
And then siply create the index as follow..
create index index_name on activitylog(columnname)
indextype is ctxsys.context
parameters ('Wordlist CYBERLAB_CTX_WLPREF lexer CYBERLAB_LEXER memory 48M');
then I am able to do something like the following..
select count(*) from ACTIVITYLOG where contains (DESCRIPTION, '<%.htm@') > 0;
hope this helps..
