Hi Karl,
Where is the introduction of below algorithm? Thanks.
"Very simple algorithmic solutions usually involve ranking top senstances
by looking at distribution of terms in sentances, paragraphs and the

Compare with classical VSM, lucene just ignore the denominator (|Q|*|D|) of
similarity formula,
but it add norm(t,d) and coord(q,d) to calculate the fraction of terms in
Query and Doc,
so it's a modified implementation of VSM in practice.
Do you just want to verify which implementation of VSM in "

I guess you can implement createBitSet() more effciently by using
Filer,but not BooleanQuery

Hi Michael,
I guess the hotspot of lucene is
org.apache.lucene.search.IndexSearcher.search()
Hi Jamie,
What's the original text size of a million emails?
I estimate the size of an email is around 100k, is this true?
When you doing search, what kind keywords did you input, words or short
