Highlighter and Phrase Queries

Hi@all

 

I am searching for a solution to make the Highlighter run property in
combination with phrase queries.

 

I want to highlight text with a phrase query like "windows printserver",
the following highlighted:

 

"windows printservers" are good blah blah "windows" manages
"printserver" blah blah, so the phrases

and the single terms are highlighted, but I just want to highlight the
phrases. How could this be done?

 

Thanks in advance

 

Mirko

Right, it will work the same as the standard Highlighter except that it 
highlights spans and phrase queries based on position.

Ok, i will do.

I guess it will also work with BooleanQueries and combined Term/Wildcard/Phrase Queries?

Check out the unit tests for the highlighter and there are a bunch of 
examples.

Its pretty much the same as using the standard scorer, except that it 
requires a cached token filter so that the tokenstream can be read more 
than once.

Once you pass in the SpanScorer to the Highlighter though, it works just 
like the non phrase/span aware Highlighter.
