----------------------------------

             Summary: CollapsingQParserPlugin ranks incorretly when 3 or more sort params
are used
                 Key: SOLR-6168
                 URL: https://issues.apache.org/jira/browse/SOLR-6168
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.7.1
            Reporter: Umesh Prasad


CollapsingQParser Plugin ranks documents incorrectly when more than 2 sort fields are used.
   I have attached a test case, which demonstrates the broken behavior when 3 sort fields
are used.

The failing test case patch is against Lucene/Solr 4.7 revision  number 1602388

PS :     SOLR-5408 fixed the issue with sorting only for two sort fields, by allowing one
to specify max/min=<field-name>. However that requires 2nd sort field to be a numeric
field. It will not work with string field or function query sort.
