             Summary: Add tag/exclude functionality to the ExpandComponent
                 Key: SOLR-5829
                 URL: https://issues.apache.org/jira/browse/SOLR-5829
             Project: Solr
          Issue Type: New Feature
          Components: SearchComponents - other
            Reporter: Joel Bernstein
             Fix For: 4.8


Adding tag/exclude functionality to the ExpandComponent would allow it to operate independently of the CollapsingQParserPlugin. For example:

q=*:*&fq={!tag=parent}type=parent&expand=true&expand.field=group_id&expand.exclude=parent

The query above searches all documents limiting the results to type=parent. So the main result would contain only parent documents.

The expand component then excludes the type=parent filter and expands the groups based on the group_id field. 

Using this approach the main search result will contain only documents with type=parent and the expanded results will display the child documents for the group.
