Re: Need help with full text index configuration

Tom,

Thanks for the quick reply.   Doing a frontend mapping was my next option since I really don't care about / and the
abilityto search on it.   Preventing the parser from using the file tokenizer seemed like a better solution so I wanted
togo down that path first (there are other false hits i was worried about too, like email, etc) 

I'm really confused about what "ALTER TEXT SEARCH CONFIGURATION dict DROP MAPPING FOR file" actually does.   The
documentationseems to make it sound like it does what I want, but I guess it does something else.
