[Xapian-discuss] Stemming and Query Parsing

[Mike Boone]

Hi Olly,

I wasn't able to find C_isnotsign in the xapian-core code...can you point me
to it? I did find some code that looks like it handles the extra characters
in the function yylex2() of queryparser.cc (also in queryparser.yy - what's
a .yy file?). Is this the correct place to modify the code, or should I look
elsewhere?

Thanks,
Mike.

Are you indexing "c#" as a term?  Our indexers (omindex and scriptindex)
currently don't (which ought to be fixed next time we make indexing
changes), and the QueryParser is set up in line with this - there's no
point it generating search terms not in the index.

If you do have "c#" as a term, you'll have to modify the queryparser
source for now as this isn't currently configurable.  Look for the call
to C_isnotsign - currently this keeps trailing + and - in the term (e.g.
C++, Cl-, Mg2+).  You also want to allow "#" here.
