Custom highlighter with lucene

By default the lucene highlighter highlights the search string using bold tags. Can I provide my own highlighting scheme, using some other color for highlighting?

If you're using just the regular Highlighter, you can pass it the SimpleHTMLFormatter constructed with whatever pre and post tags you want:

new Highlighter(fragmentScorer, new SimpleHTMLFormatter("<span>", "</span>"));

Of course, there are other formatters, like the GradientFormatter, that will highlight the term with based on a minimum and maximum color determined by score, all which you can set via the constructor. The SpanGradientFormatter does something similar, as well.
