----------------------------------
Summary: DefaultSolrHighlighter can sometimes avoid
CachingTokenFilter
Key: SOLR-6680
URL: https://issues.apache.org/jira/browse/SOLR-6680
Project: Solr
Issue Type: Improvement
Components: highlighter
Reporter: David Smiley
Assignee: David Smiley
Fix For: 5.0
The DefaultSolrHighlighter (the most accurate one) is a bit over-eager to wrap
the token stream in a CachingTokenFilter when hl.usePhraseHighlighter=true.
This wastes memory, and it interferes with other optimizations -- LUCENE-6034.
Furthermore, the internal TermOffsetsTokenStream (used when TermVectors are
used with this) wasn't properly delegating reset().
