Thanks a lot.
I used the lucene analyzer to parse the profile and everything works :)

Oggetto: Re: Retrieve found keywords from document

You could parse the output from the lucene analyzer that you are using
to get hold of a list of terms and pick the ones that are hobbies.  Or
do it outside lucene using whatever string parsing technique you like.

Or take a look at the recent thread on this list on a similar topic:
"High frequency term for the searched query".
