      Description

      SOLR-2058 subtly changed how phrase queries, created through the pf, pf2 and pf3 parameters, are merged into the main user query.

      For the query: 'term1 term2' with pf2:[field1, field2, field3] we now get (omitting the non phrase query section for clarity):

      <main query>
      DisjunctionMaxQuery((field1:"term1 term2"^1.0)~0.1)
      DisjunctionMaxQuery((field2:"term1 term2"^1.0)~0.1)
      DisjunctionMaxQuery((field3:"term1 term2"^1.0)~0.1)
      

      Prior to this change, we had:

      <main query> 
      DisjunctionMaxQuery((field1:"term1 term2"^1.0 | field2:"term1 term2"^1.0 | field3:"term1 term2"^1.0)~0.1)
      

      The upshot being that if the phrase query "term1 term2" appears in multiple fields, it will get a significant boost over the previous implementation.
