pf (Phrase Fields) and ps (Phrase Slop) related to each other. Lets say you have &q=term1 term1&pf=title text&ps=10 We can think as if dismax adds title:"term1 term2"~10 text:"term1 term2"~10 imaginary optional clauses to your original query. Optional means they effect order of documents. http://wiki.apache.org/solr/DisMaxQParserPlugin#pf_.28Phrase_Fields.29
