is it somehow possible to get a "highlighting" on fields?

i am not interested in the real term that is matched, i just want to know  
in which field the query matched.

i experimented a little with highlighting, but it's pretty slow with fields  
that have 10.000+ terms in it. the query then takes 90seconds instead of  
1second.  
even reducing the number of fragments etc did not help pretty much.

i also read about the fast-vector-highlighter, but is there another way to  
speed this up?

There is an issue in Lucene 3.5 that affects highlighting performance on  
queries with very large number of  
terms: [[LUCENE-3719] FVH: slow performance on very large queries - ASF JIRA](https://issues.apache.org/jira/browse/LUCENE-3719)

It's fixed in Lucene 3.6, which is used by elasticsearch 0.19.3. You can  
try 0.19.3-SNAPSHOT to see if it speeds things up.
