------------------------------------
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.
