> Key: SOLR-16111
> URL: https://issues.apache.org/jira/browse/SOLR-16111
> Project: Solr
> Issue Type: New Feature
> Components: highlighter
> Reporter: Christine Poerschke
> Assignee: Christine Poerschke
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h

> Use case: a search referencing multiple fields and highlighting is required for one of the fields: {{q=fieldA:one OR fieldB:two OR fieldC:three}} {{hl.fl=fieldA}}
> * {{hl.requireFieldMatch=true}} can be used if highlighting of the terms ("two", "three") from the fieldB and fieldC is a problem.
> * {{hl.q=fieldA:one OR fieldB:two}} can be used if highlighting of the fieldB term is good but fieldC terms are a problem.
> _New feature:_ {{hl.queryFieldPattern=fieldA,fieldB}} as an alternative to {{hl.q=fieldA:one OR fieldB:two}} e.g. if obtaining {{hl.q}} from {{q}} poses complexity.
> There's already a TODO comment present in the code regarding this: https://github.com/apache/lucene-solr/blob/releases/lucene-solr/8.11.1/solr/core/src/java/org/apache/solr/highlight/UnifiedSolrHighlighter.java#L418
> {code}
> // TODO define hl.queryFieldPattern as a more advanced alternative to hl.requireFieldMatch.
> {code}
