Hi,

Right now you must either use the form foo AND bar or +foo +bar
to accomplish what you want to do before you send the query to the
QueryParser.

Another alternative is to parse the query yourself and then create the
queries using the BooleanQuery with the required flag set. This is
somewhat difficult if you want to keep all the current QueryParser
functionality.
One last option is to copy the current QueryParser and modify it to meet
your needs.

Hope this helps.

Isn't it standard that if the user wants all words to match they will use
the AND keyword? (Lucene supports this) If you want all words to match all
of the time, why not just split the query with a StringTokenizer and put it
back together with the + ? That should only be five or ten lines of code...

Or, of course, you could add a checkbox for the user that was labeled
'match all words' and do the above only in the condition of that box being
checked..
