Juan, Pay close attention to the boundary scanner you’re employing:
http://wiki.apache.org/solr/HighlightingParameters#hl.boundaryScanner You can be explicit to indicate a type (hl.bs.type) with options such as CHARACTER, WORD, SENTENCE, and LINE. The default is WORD (as the wiki indicates) and I presume this is what you are employing. Be careful about using explicit characters. I had an interesting case of highlight returns that looked like this: > This is a highlight > Here is another highlight > Yes, another one, etc… It was a bit maddening trying to figure out why “>” was in the highlight…turned out it was XML content and the character boundary clipped the trailing “>” based on the boundary rules. In any case, you should be able to achieve a pretty flexible result depending on what you’re really after with the right combination of settings.
