Subject Re: New Query Type(s)
Date Sat, 14 Feb 2004 01:10:12 GMT
Hi Doug,
did you implement such a feature yet? I know i am bothering you with these phrasequery issues...sorry...
and, thank you. We all appreciate you.


PS: search engine that support that use a sintax like:
"a b c" w/10 "a f g" 
for this type of query, users do not like to use "(" much.

This was not a stupid request, but a reasonable one.  In fact I 
currently have a contract to implement such a feature.  It should show 
up in the next month or so.
