Xapian discuss - Mar 2007 - Making '.' a valid search term character

Hey
Is there any way to make the queryparser not split queries on '.'?  
I'm using Xapian for the search on http://osx.iusethis.com/ and some  
mac apps have dots in their names. I've been able to index terms with  
'.' in them, but queryparser splits the search on them.

It's not currently configurable, but it's not hard to patch the code to
do this.

Look in queryparser/queryparser_internal.cc for where '&' is
handled.
We treat a single embedded '&' as a word character so things like
"AT&T"
are a single word (but C code like "a&&b" isn't).  If you
change that to
check for '&' or '.' then you'll probably get the effect
you want.

There's also code to handle "initialisms" specially, so
"I.B.M." is
treated the same as "IBM".  That only applies to single capitals with
'.' in between, but you might want to disable that if it's likely to
be a problem for you (it's just above where '&' is checked for).
