I've done a bit with PyLucene and term frequencies, to make the query
expansion described at <http://hublog.hubmed.org/archives/001304.html>.
The code was something like:
for i in range(0, max):
j = hits.id(i)
tfv = reader.getTermFreqVector(j, 'fieldname');
if (tfv):
terms = tfv.getTerms();
freqs = tfv.getTermFrequencies();
for k in range(0, len(terms)):
term = terms[k]
freq = freq[k]
and then for each unique term:
t = Term('fieldname', term)
df = reader.docFreq(t)
