Isn't it semi trivial if you are not interested in the fragments (I
swear it seems that most people are not)? Isn't it you that suggested
turning the query into a SpanQuery, extracting the spans and then doing
the highlighting after a rewrite? This seems somewhat trivial so what am
I missing? I have started a simple implementation of this, but stopped
short of combining the highlight spans (seems like a nasty n^2 problem
that I don't know a good algorithm around - every new highlight has to
be compared against every previous highlight for overlap : I am sure
your the man to ask about this). I plan on getting back into this soon.
Not trivial? Or do you just mean with the fragments...you seem to be
deeply interested in fragments but a lot of people seem to just want to
highlight the source text.
Any words of wisdom would be sorely appreciated.

This is a deficiency in the highlighter functionality that has been

Hi,
I'm wondering what the best way is to do highlighting of multiword
phrases.
For example, if a search is for "president kennedy", how can I make sure
that "president" is only highlighted if it is next to "kennedy" and
"president" in "president clinton" is not.
I haven't figured out where in the process the phrases are being
split into
separate words.
Would restructuring the query that is passed to the scorer help with
this?
It's currently a set of boolean queries with each phrase as a separate
query. Or should the exact phrases be set up as WeightedTerms?
Thanks!
Anne
