Mikhail Khludnev created SOLR-6234:
--------------------------------------
Summary: Scoring modes for query time join
Key: SOLR-6234
URL: https://issues.apache.org/jira/browse/SOLR-6234
Project: Solr
Issue Type: New Feature
Components: query parsers
Affects Versions: 5.0, 4.10
Reporter: Mikhail Khludnev
Attachments: lucene-join-solr-query-parser-0.0.2.zip
it adds {{scorejoin}} query parser which calls Lucene's JoinUtil underneath. It
supports:
- {{score=none|avg|max|total}} local param (passed as ScoreMode to JoinUtil),
also
- supports {{b=100}} param to pass {{Query.setBoost()}}.
So far
- it always passes {{multipleValuesPerDocument=true}}
- it doesn't cover cross core join case, I just can't find the multicore
testcase in Solr test, I appreciate if you point me on one.
- I attach standalone plugin project, let me know if somebody interested, I
convert it into the proper Solr codebase patch. Also please mention the
blockers!
