> As a consequence of LUCENE-6590, {{MoreLikeThisHandler}} was changed in
> r1701621 to use the new API. In SOLR-7912, I adapted that code for
> {{CloudMLTQParser}} and {{SimpleMLTQParser}}. However, setting the {{boost}}
> parameter just failed for me after updating to 5.4 with the following error
> message:
> {code}
