Highlighting bug?

Elastic Stack Elasticsearch
1

A query wrapped in a "constant_score" inside a "should" of a "bool" doesn't
highlight. inside a "must" it does and without the "constant_score" it does
too. Is this intentional or a bug? If it's intentional, what is the
reasoning behind it...?

Here is a gist demonstrating this: https://gist.github.com/3899939

I think this is a "limitation" / "bug" in ES. The lucene highlighter
doesn't support this at all out of the box and the ES highlighter only
supports the must case since it optimizes the boolean query if it only has
a single clause. can you create an issue for this problem on github?

FYI - I created an issue in Lucene land and provided a fix for this.
([LUCENE-4486] Highlighter doesn't support ConstantScoreQuery - ASF JIRA). The elasticsearch
issue is here: Highlighting fails for ConstantScoreQuery · Issue #2332 · elastic/elasticsearch · GitHub I
will provide a PR soon so this should work in upcoming releases. Thanks for
reporting this!

Thanks! No problem, my collegue Ernst Bunders ran into this, I just
reported it and wrote the test.
