Indexing Problem with FILE_DATASTORE and .pdf files

Question

Hello all,
Do any of you have an example showing how to index .pdf files through FILE_DATASTORE? I am able to successfully index text and .doc files but not a .pdf file. Below is the script that I use to index my files:
create index myindex on mytable(docs)
indextype is ctxsys.context
parameters ('datastore COMMON_DIR filter ctxsys.null_filter');
I am using Oracle 8.1.6
Thanks you!!!

I don't think that you are able to index anything else then plain ascii texts, because you are not using the INSO filter.
Use preferences like this:
exec ctx_ddl.drop_preference('NO_PATH');
exec ctx_ddl.create_preference('NO_PATH','FILE_DATASTORE');
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');
drop index i_filenames;
create index i_filenames on filenames (filename)
indextype is ctxsys.context
parameters ('datastore NO_PATH
section group MY_SECTION
lexer MY_LEXER
filter MY_FILTER
memory 10M
IMPORTANT is the INSO_FILTER preference.
