Hi Yannick,
More like this (mlt) stuff does this already.
It extracts "interesting terms" from top N documents.
Don't remember but this feature may require "term vectors" to be stored.

Hi !
I am using (Java) Lucene for data indexation, and I want to produce kind
of tags cloud for specific data.
I've found HighFreqTerms to get a top list of terms from *all
documents* (if I have well understood) (by the bye, I had override it to

TermVectorMapper,
I suspect.

Hello everyone. I've been fiddeling with the idea of retrieving the top
terms from a subset of the index (i.e. top terms from the documents
retrieved by a given search). This could for instance be useful to
identify top ranking terms in a given datespan etc.
It would be something

hello,
how do we get the terms with the highest frequency for a given field?
I know one can TermEnum terms = searcher.getIndexReader().terms() then,
iterate over it and filter the fields required and count them,
but is there a way to get lets say top 50 terms for a given field without
iterating?

Erm.. if its not tokenized that's your problem.
You are setting up an Analyzer when indexing.. but then not actually
USING it.
Whereas when you are searching you are running your query through the
analyzer, which transforms your text in such a way that it no longer
matches against your untok

Oh and the field is not tokenized and stored.

Can someone explain this to me?
After indexing I can see the terms I expect in the top terms using Luke but
then when I search I get no results??
This is really bizarre and is blocker for me.
Thanks.
