Hello,

Did you get it to work eventually?

Try setting hl.weightMatches=false and see if that helps.  Wether this
helps or not, I'd like to have a deeper understanding of the internal
structure of the Query (not the original query string).  What query parser
are you using?.  If you pass debug=query to Solr then you'll get a a parsed
version of the query that would be helpful to me.
