[jira] [Commented] (SOLR-9267) Cloud MLT field boost not working
[ https://issues.apache.org/jira/browse/SOLR-9267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15581365#comment-15581365 ]
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.

> 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}
