---------------------------------
It is perhaps worth noting that these are made against the 4x branch.
> 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
>
> Attachments: SOLR-5827.patch, SOLR-5827.patch
>
>
> 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.
