Well I use results that have a name match as more important than ones with a
company match, and ones with both are the most important.  I was hoping term
boosting would help me mathematically detect these cases (for example, a
firstname + company match would have detectably higher score) without having
to use a highlighter for what is clearly not its purpose.  I also am not
using a traditional search display, so every result I find is important and
there is no pagination (it's a background search).

Is it possible to do this with term boosting?  Otherwise my highlighter
solution works for the time being, it's just slow.

Thanks,
Max
