I got it fixed now I think. I thought that if you used it like "hl.q=spell Checker" it would use the query analysis of the field that was being highlighted as default. But in my case it needs to be "hl.q=content_hl:(spell Checker)" for it to work. The behavour I got default made no sense whatsoever.
Right. You can also use localParams for hl.q.
Could you be so kind to explain a bit more how hl.q is supposed to work and with some examples?
My motivation was described here when I proposed hl.q: https://issues.apache.org/jira/browse/SOLR-1926 But I think hl.q can be used to overwrite q for highlighting. For example, if q is a boolean query of "A AND B", you can expand it to "A AND B AND C" or shrink it to "A" for hl.q. koji -- http://www.rondhuit.com/en/
