After you get the query object, you can use IndexSearcher's function
docFreq(), like this
final Set<Term> terms = new HashSet<Term>();
query = searcher.rewrite(query);
query.extractTerms(terms);
for(Term t : terms){
int frequency = searcher.docFreq(t);
}

I need to find the most frequent terms that are appeared with a query.
HighFreqTerms.java can be used only to obtain the high frequency terms in
the whole index.
I need just to find the high frequency terms to the submitted query.
What I do now is:
I search the index with the query and retrieve the relevant documents then
save those documents in a new folder then index them. At the end I use
HighFreqTerms.java in the new index so I can find the most frequent terms to
the query. However, this is very slow and need long time to run.
Any idea how I can do this task efficiently
Thanks in advance
