I think you are asking collection frequency of a term. Term Frequency is
defined between a document and a term which is printed in the loop in the
following code. And at
Given a term say "apache", I want to look up the lucene index
programmatically to find out its frequency in the corpus.

Hi,
You didn't mention if you were looking for something programmatic or not, but
there's a tool called "Luke", and when you start that up and point it to your
index
How to get the number of times a term occurs in the Lucene index?

You need to make sure you are indexing with Term Vectors in order for
IndexReader.getTermFreqVector to return anything meaningful. You do not
need to implement it.
QueryTermVector is meant to provide similar information to the Document
side for Queries.
For an example demo of indexing and using t

You probably don't need to implement it, it's been implemented already.
Just call the method.

freq = result.getTermFrequencies();
but I think this is a very low efficient way.
Anyone can help me ? thx

Are you looking for this?
TermFreqVector vector = IndexReader.getTermFreqVector(docNum, "field");
That gives you the frequency of ever
I search the index with a group of terms. I want to get every term's
frequency in each document of the search result.
How can I?
thx,
