For this query, highlighting does not work. Specifying hl.fl or not, does not
influence the result. The result is:
<lst name="highlighting">
<lst name="GB18030TEST"/>
<lst name="UTF8TEST"/>
</lst>

This request creates a BooleanQuery that is composed of TermQuery("inStock",
true) and BoostedQuery. Lucene's Highlighter knows TermQuery but doesn't know
how to deal with Solr's BoostedQuery. The BoostedQuery should include
TermQuery("name","test") that you want to hihglight, but Lucene doesn't care
BoostedQuery, so Highlighter ignores entire BoostedQuery.

> Key: SOLR-2632
> URL: https://issues.apache.org/jira/browse/SOLR-2632
> Project: Solr
> Issue Type: Bug
> Components: highlighter
> Affects Versions: 1.4.1, 3.2, 3.3
> Environment: Linux.
> Reproduced in different machines with different Linux distributions and
> different JDK's.
> Solr 3.3 and Lucidworks for solr 1.4.1 and 3.2.
> Reporter: Juan Antonio Farré Basurte
> Priority: Minor
> Labels: _query_, boost, dismax, edismax, embedded, highlighting,
> hl.fl, query
>
> I need to issue a dismax query, with date boost (I'd like to use the
> multiplicative boost provided by boost queries) and also filtering for other
> fields with too many possible distinct values to fit in a filter query. To
> achieve this, I use the boost query as a nested query using the pseudofield
> _query_. I also need highlighting for the fields used in the dismax query,
> but highlighting does not work. If I just use the boosted dismax query
> without embedding it inside another query, it works correctly. If I use bf
> instead of a boost query, and embed directly the dismax query, it works too,
> but hl.fl needs to be specified.
> It's a bit complicated to explain, so, I'll give examples using the example
> data that comes with solr (the problem is reproducible in the example solr
> distribution, not only in my concrete project).

> This doesn't work either. Same result.
> http://localhost:8983/solr/select?q={!boost b=$dateboost v=$qq
> defType=dismax}&qq=test&qf=name&dateboost=recip(ms(NOW,last_modified),3.16e-11,1,1)&hl=true
> In this case, hightlighting works correctly:
> <lst name="highlighting">
> <lst name="GB18030TEST">
> <arr name="name">
> <str><em>Test</em> with some GB18030 encoded characters</str>
> </arr>
> </lst>
> <lst name="UTF8TEST">
> <arr name="name">
> <str><em>Test</em> with some UTF-8 encoded characters</str>
> </arr>
> </lst>
> </lst>
> http://localhost:8983/solr/select?q=%2BinStock:true%20%2B_query_:%22{!dismax%20v=$qq}%22&qq=test&qf=name&bf=recip%28ms%28NOW,last_modified%29,3.16e-11,1,1%29&hl=true&hl.fl=name
> This also works. Same result as before. But in this case hl.fl is needed.
> Without it, highlighting does not work, either.
> Thanks.
