The Lucene PhraseQuery goes through a lot of effort to calculate "phrase
frequency" (phraseFreq) - but that is not the same as term frequency (don't
confuse terms and phrases). Feel free to pick that number out of the
debugQuery output, or from the XML variant of the explain output.
For reference, an example:
0.2169777 = (MATCH) weight(text_t:"quick brown" in 0) [DefaultSimilarity],
result of:
0.2169777 = fieldWeight in 0, product of:
1.4142135 = tf(freq=2.0), with freq of:
2.0 = phraseFreq=2.0
0.61370564 = idf(), sum of:
0.30685282 = idf(docFreq=1, maxDocs=1)
0.30685282 = idf(docFreq=1, maxDocs=1)
0.25 = fieldNorm(doc=0)
So, it is really "phraseFreq" and then Lucene treats phraseFreq as if it
were term frequency (tf) in the similarity calculation.

Subject: Re: get term frequency, just only keywords search
ok I undestand it (thanks) but if I search a sentence and type
"debugQuery=on", in the explain I obtain termFreq=2.0 and it right.
Is it possible to obtain that parameter?
