Hi All.
I want to do the same thing with say a window of 10/15.
Can some one give me more details about how to do this i.e getting
neighbors[both sides] of size "window", if some examples are there
please
point me to them/post in the mail.
Also I would like to know about the term query. Is it the case that
the term
query has to be only single term , I mean can'nt we do the same
thing where
the search query is not just a term but say a phrase[multiple
terms]. Now I
want to extract neighbors for this matched phrase. I think this is the
generic scenario.
Yes, see the Span*Query objects (SpanNear, SpanFirst, etc.)
So as per the mail I have to make use of SpanQuery, TermVector and
TermVectorMapper for these purposes, right?
That's how I've traditionally done it.
NB:I also want to add hit highlighting after fixing the neighbor
problem.
Thanks,
KK.

(although
I think you can do better than the code in the third reply by using a
TermVectorMapper such that you can process the TermVector as it
comes from
disk.)
Essentially, you need to use a combination of SpanQuery, TermVector
and
TermVectorMapper.

Hi all,
I want to get the word before and the word after the matched
Term.For
Example if i have the Text " The drug was freshly prepared at 4-hour
intervals . Eleven courses were administered to seven patients at
this dose
level and no patient experienced nausea or vomiting" and the
matched Term
for example "patient" i want to get the word level and the word
experienced("and" and "no" are stop words, therefore i d'ont want
to get
them.).I have looked at the Class Termposition but in this Class i
can only
get the position of the matched Term, how can i get the word
before and
after it, any suggestion?.
Thank you in advance.
Kamal
