-----------------------------------
Summary: Teach fast FastVectorHighlighter to highlight "child
fields" with parent fields
Key: LUCENE-5274
URL: https://issues.apache.org/jira/browse/LUCENE-5274
Project: Lucene - Core
Issue Type: Improvement
Components: core/other
Reporter: Nik Everett
Priority: Minor
I've been messing around with the FastVectorHighlighter and it looks like I can
teach it to highlight matches on "child fields". Like this query:
foo:scissors foo_exact:running
would highlight foo like this:
<em>running</em> with <em>scissors</em>
Where foo is stored WITH_POSITIONS_OFFSETS and foo_plain is an unstored copy of
foo a different analyzer and its own WITH_POSITIONS_OFFSETS.
This would make queries that perform weighted matches against different
analyzers much more convenient to highlight.
I have working code and test cases but they are hacked into Elasticsearch. I'd
love to Lucene-ify if you'll take them.
