-----------------------------------
Summary: 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: 5.5.2, 5.5.1, 5.5
Reporter: Brian Feldman
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:
if (localParams.get("boost") != null) {
mlt.setBoost(localParams.getBool("boost"));
boostFields = SolrPluginUtils.parseFieldBoosts(qf);
qf = boostFields.keySet().toArray(qf);
}
