      Description

      It would be useful for the CollapsingQParserPlugin to support ValueSource collapse criteria.

      Proposed syntax:

      fq={!collapse field=collapse_field max=value_source}
      

      This ticket will also introduce a function query called "cscore", which will return the score of the current document being collapsed. This will allow score to be incorporated into collapse criteria functions.

      A simple example of the cscore usage:

      fq={!collapse field=collapse_field max=sum(cscore(), field(x))}
