SOLR-2058:  changes to reflect feature set committed to Trunk/4.0

  <!> [[Solr4.0]] You can also specify an optional slop factor directly in "pf" with
the syntax {{{field~slop}}}. To specify both a slop and a boost, use {{{field~slop^boost}}}.
Example: {{{title~2^10.0}}} will use the title field with a phrase slop of 2 and a boost of
10.0. A phrase slop specified here overrides the default specified in "ps". See SOLR-2058.
  
  === ps (Phrase Slop) ===
- Amount of slop on phrase queries built for "pf" fields (affects boosting).
+ Default amount of slop on phrase queries built with "pf", "pf2" and/or "pf3" fields (affects
boosting).
  
  === pf2 (Phrase bigram fields) ===
  As with 'pf' but chops the input into bi-grams, e.g. "the brown fox jumped" is queried as
"the brown" "brown fox" "fox jumped"
  
- === ps2 (Phrase bigram slop) ===
- <!> [[Solr4.0]]. See SOLR-3351
- 
- As with 'ps' but sets default slop factor for 'pf2'. If not specified, 'ps' will be used.
- 
  === pf3 (Phrase trigram fields) ===
  As with 'pf' but chops the input into tri-grams, e.g. "the brown fox jumped" is queried
as "the brown fox" "brown fox jumped"
- 
- === ps3 (Phrase trigram slop) ===
- <!> [[Solr4.0]]. See SOLR-3351
- 
- As with 'ps' but sets default slop factor for 'pf3'. If not specified, 'ps' will be used.
  
  === tie (Tie breaker) ===
  Float value to use as tiebreaker in !DisjunctionMaxQueries (should be something much less
than 1)
