For example, if I have terms A, B and C and I do a simple boolean search

B C, I would like to have a query that behaves a bit like if I rewrote this
query as such :
+A +B +C "A B" "B C" "A B C"
This would boost results where the exact string "A B C" or any substring
like "A B" or "B C" are found.
You could extend ExactPhraseScorer and override phraseFreq() to first
compute a (weighted) sum the freq() of each TermPositions in the
PhrasePositions. The weighting should probably be something like
sqrt(freq)/idf(term).
