Ron Mayer commented on SOLR-2058:
---------------------------------
Totally agree that that was a bizarre way I used of encoding the boost.
I did that on my first draft just to minimize the impact with the rest of the
code (where some functions were expecting the "Map<String,Float>" pieces).
I'll post an updated patch with a more sane class like the one you described.
I'm new enough to the code that I'm not sure where such a class should reside.
Any opinions?

> ... 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 [the query]:
> "red hat black jacket"
> boosts only documents with "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.
