Upayavira created SOLR-5827:
-------------------------------
Summary: Add boosting functionality to MoreLikeThisHandler
Key: SOLR-5827
URL: https://issues.apache.org/jira/browse/SOLR-5827
Project: Solr
Issue Type: Improvement
Components: MoreLikeThis
Reporter: Upayavira
Fix For: 4.8
The MoreLikeThisHandler facilitates the creation of a very simple yet powerful
recommendation engine.
It is possible to constrain the result set using filter queries. However, it
isn't possible to influence the scoring using function queries. Adding function
query boosting would allow for including such things as recency in the
relevancy calculations.
Unfortunately, the boost= parameter is already in use, meaning we cannot
replicate the edismax boost/bf for additive/multiplicative boostings.
My patch only touches the MoreLikeThisHandler, so the only really contentious
thing is to decide the parameters to configure it.
I have a prototype working, and will upload a patch shortly.
