Using intermedia text

Question

Hello,
I'm working on a website at the moment which is cgi based and has an Oracle 8i backend.
On this website users can upload word documents etc into an knowledge base. These documents are physically held on the file system
What I want to do is to upload the documents to an Oracle table and then use intermedia text to search on these documents. I would like to avail of intermedia Themes & Gists and the "ranking" system it uses. In other words I would like the search to return something similar to the search results you find in Oracle Portal.
Any information on how to incorporate oracle intermedia into an existing cgi based website would be much appreciated.
thank you.

Hi,
For documentation see here on technet: products -> Oracle Text.
You don't have to load the documents into the database when they are already in the filesystem.
You can create a table with an entry for each filename.
Here is a sample script for FILE_DATASTORE with INSO FILTER (for filtering word and other documents).
=========================================================
-- Sample INSO Filter and FileDatastore
drop table datastores;
create table datastores(id number primary key, docs varchar2(2000));
insert into datastores values(1,'whitepaper.pdf');
commit;
-- Create Preferences
exec CTX_DDL.drop_preference('MY_LEXER');
exec CTX_DDL.create_preference('MY_LEXER','BASIC_LEXER');
exec CTX_DDL.set_attribute('MY_LEXER','BASE_LETTER','YES');
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_section_group ('MY_SECTION');
exec ctx_ddl.create_section_group ('MY_SECTION','NULL_SECTION_GROUP');
exec ctx_ddl.drop_preference('COMMON_DIR');
exec ctx_ddl.create_preference('COMMON_DIR','FILE_DATASTORE');
exec ctx_ddl.set_attribute('COMMON_DIR','PATH','/tmp/pdf');
exec Ctx_Ddl.Drop_Preference ('inso_filter_pref');
exec Ctx_Ddl.Create_Preference ('INSO_FILTER_PREF', 'INSO_FILTER');
-- Create Text Index
-- drop index datastores_text;
exec ctx_output.start_log('index.log');
create index datastores_text on datastores (docs)
indextype is ctxsys.context
parameters ('datastore COMMON_DIR
filter INSO_FILTER_PREF
lexer MY_LEXER
section group MY_SECTION
memory 50M');
exec ctx_output.end_log;
select count(*) from dr$datastores_text$i;
select token_text from dr$datastores_text$i;
