my results might
be even better if I had a couple different "pf2"s with different "ps"'s
at the same time.
In particular. One with ps=0 to put a high boost on ones the have
the right ordering of words. For example insuring that:
"red hat black jacket"
boosts only red hats and not black hats.
And another pf2 with a more modest boost with ps=5 or so to handle
the query above also boosting docs with "red baseball hat".

Perhaps fold it into the pf/pf2 syntax?
pf=text^2 // current syntax... makes phrases with a boost of 2
pf=text~1^2 // proposed syntax... makes phrases with a slop of 1 and
a boost of 2
That actually seems pretty natural given the lucene query syntax - an
actual boosted sloppy phrase query already looks like
text:"foo bar"~1^2

Big +1 to this idea ... the existing "ps" param can stick arround as the
default for any field that doesn't specify it's own slop in the pf/pf2/pf3
fields using the "~" syntax.
