You run your SpanQuery, and get back the Spans. From there, you need
to load the document (either by reanalyzing the tokens or by using
Term Vectors) and then you just have to setup your window around the
position match. Unfortunately, I don't think there is a better way in
Lucene to get those terms in a window around a given position. You
might be able to if you altered Lucene to support moving both forward
and backwards over positions, but I am not sure how difficult this is
to do w/o looking more into it (and it isn't high on my list at the
moment.)
Also, I adhere to Hoss' philosophy on private email:

Hi, thanks for the reply.
But can anyone give me some more hints? I have checked SpanQuery,
but still
haven't found out a solution.
Thanks.

Have a look at SpanQuery and it's derivatives. You will need to do
some post-processing as well.

Hi all,
I want to compute the co-occurence frequency between a word and a
phrase(
this phrase contains some words, and the words in it should be
successive
and in order). It's like an NEAR operation (like setting slop at
3...)
Does anyone know how to implement this?
Thanks in advance.
