Ere Maijala commented on SOLR-9267:
-----------------------------------
I'm moving my patch to address this to SOLR-9644 since the same functionality
in the SimpleMLTQParser is affected too.
> Cloud MLT field boost not working
> ---------------------------------

> Key: SOLR-9267
> URL: https://issues.apache.org/jira/browse/SOLR-9267
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: MoreLikeThis
> Affects Versions: 5.0, 5.1, 5.2, 5.2.1, 5.3, 5.3.1, 5.3.2, 5.4, 5.4.1,
> 5.5, 5.5.1, 5.5.2, 5.5.3, 5.6, 6.0, 6.0.1, 6.0.2, 6.1, 6.1.1, 6.2

> When boosting by field "fieldname otherFieldName^4.0" the boost is not
> stripped from the field name when adding to fieldNames ArrayList. So on line
> 133 of CloudMLTQParser when adding field content to the filteredDocument the
> field is not found (incorrectly trying to find 'otherFieldName^4.0').
> The easiest but perhaps hackiest solution is to overwrite qf:
> {code}
> if (localParams.get("boost") != null) {
> mlt.setBoost(localParams.getBool("boost"));
> boostFields = SolrPluginUtils.parseFieldBoosts(qf);
> qf = boostFields.keySet().toArray(qf);
> }
> {code}
