Yeah. The last post got me to reading more about BooleanQuery and this
opend up the flood gates. 

A question on the heels of this one though. I have documents indexed in
multiple fields. Lets say Name, Synonym, and Definition. Lets say the
search phrase is "big green cat". What I'm building using the
BooleanQuery object is:

	+((Name:big Name:green Name:cat) (Synonym:big Synonym:green
	(Definition:big Definition:green Definition:cat)) 

I'm getting too many 100% hits back when the search term is say "cat". I
want a Query that is more descerning, so that the term "cat" returns a
hit but less than 100%. The term "big green cat" should return 100%, the
term "big green" or "green big" should return something less than 100%
and then term "big" or "green" or "cat" something less that the previous
one. Hope this makes since.

Are you simply looking to use multiple terms in your search?  In that
case, simply use BooleanQuery instead of TermQuery.  QueryParser will
recognize strings like    foo AND bar    or    +foo +bar    and turn
that into a BooleanQuery for you.
