You can use the value of Integer.MAX_VALUE instead of 3 in your example,
something like:
+red +fox +"red fox"~2147483647^10
Nutch does that I think (you might want to search the archives), but I have no
clue how fast/slow it is.

Subject: Using Proximity for Ranking
Dear Lucene-Users,
is there any possibility to use proximity for long queries (10 and more
terms) automatically? I need a kind of ranking feature, that would give
higher relevance scores to those documents, that contain query terms (or
some of query terms) with a lower distance between them. I know that I can
use the slop operator for phrase search ("red fox"~3), but what I need
should work for partial matching as well.
