Description

Range queries against multi-valued string fields produces useless highlighting, even though "hl.highlightMultiTerm":"true"

I have uncovered what I believe is a bug. At the very lease it is a difference in behavior between Solr v5.1.0 and v7.5.0 (and v7.7.1).

I have a multi-valued string Field defined in my schema as:

<fieldType name="string" class="solr.StrField" sortMissingLast="true"/>
<field name="MyStringField" type="string" indexed="true" stored="true" multiValued="true" />

I am using a query containing a Range clause and I am using highlighting to get the list of values that actually matched the range query.

All examples below were using the appropriate Solr Admin Server SolrCore Query page.

• is caused by: SOLR-8037 speed up term range queries, use filter cache for embedded ranges
• requires: LUCENE-8848 UnifiedHighlighter should highlight all Query types that implement Weight.matches
