Right... seems like the type of stuff that dismax does... treat the query as more of a user query and expand to different low level query types (maxdisjunction, sloppy phrase, etc) to increase relevance. -Yonik

Re: prefixquery, phrasequery support in solr
Ok, let me show an example. Assume, I want to perform the following
search: cat AND dog. I can perform it 3 different ways:
a) simply search for: cat AND dog (cat +dog)
b) search for: cat dog (assuming schema.xml has
c) search for: cat dog (passing q.op=AND query parameter to the
requesthandler).
I am wondering I can do something similar to b) and c) if I want
to perform a prefix query (of phrasequery)...
Ideally, I would like to have a parameter similar to defaultOperator,
like defaultQueryType which can take on values PREFIXQUERY, PHRASEQUERY
in which case the query string won't be parsed by QueryParser and will
interpreted as a prefix query. E.g., assume I have
in my schema.xml
and I search for: solr, then it will be interpreted as the solr* query
in the current context (which is a prefix search, because currently
the queryparser parses the query string by default).

I'm having a little trouble understanding what you mean ... can you
elaborate with some examples (both of what the configuration would look
like, and what hte behavior would be with some example inputs)
