Highlighting with Span queries

[Sjoerd Smeets]

Hi all,

I am trying to get highlighting working with Span queries. My span query
looks like (my query parser is an extension of the edismax queryparser):

*spanNear([stemmed_text:tintin, stemmed_text:haddock], 4, false)*

When I change the query to
*+stemmed_text:tintin +stemmed_text:haddock*

I get highlights. I'm using the unified highlighter and also I tried
setting the usePhraseHighlighter explicitly with no luck.

Should highlighting be supported and if so, am I missing something?

Thanks!
Sjoerd

unstemmed_text schema:
*<dynamicField name="unstemmed_*" type="unstemmed" indexed="true"
multiValued="true" stored="true" storeOffsetsWithPositions="true"/>*

highlight component:
