Short summary:

   Is there any way I can specify that I want a lot
   of phrase slop for the "pf" parameter, but none
   at all for the "pf2" parameter?

I find the 'pf' parameter with a pretty large 'ps' to do a very
nice job for providing a modest boost to many documents that are
quite well related to many queries in my system.

In contrast, I find the 'pf2' parameter with zero 'ps' does
extremely well at providing a high boost to documents that
are often exactly what someone's searching for.

Is there any way I can get both effects?

Edismax's pf2 parameter is really nice for boosting exact phrases
in queries like 'black jacket red cap white shoes'.   But as soon
as even a little phrase slop (ps) is added, it seems like it starts
boosting documents with red jackets and white caps just as much as
those with black jackets and red caps.

My gut feeling is that if I could have "pf" with a large phrase
slop and the pf2 with zero phrase slop, it'd give me better overall
results than any single phrase slop setting that gets applied to both.

Is there any good way for me to test that?

  Thanks,
  Ron
