Well a bit strange as this is the 1st time, I am not receiving any reply
to the question even after sending it again.
Would be very helpful if someone can throw some light on the problem.

Hello.
This might be a long mail but I have mentioned everything very
clearly so that I can get needed assistance.
Indexing:
I have a use case. I am indexing two fields.
Field 1 : Value. Say suppose 1,2,3,4,5 etc..
Field 2 : Time in Long Format . Say 20131203010005, 20131203132332
etc..
Both the field values are extracted from number of documents. Each
document contains N number of such entry.
Indexing is not a problem. I am able to index both the fields properly.
Search:
Construction of Query:
During searching, I want that given a value (for field 1 say E.g. 2),
get me the count of occurence of 2 each hour in the given index. i.e.
From 20131203000000-20131203005959 and then from
20131203010000-20131203015959..
I gave first field in TermQuery. and for second I used NumericRange
Query -creating query for 24 time slots in a day.
Created a Boolean Query and gave TermQuery and NumericRange Query as
two clauses with MUST and executed.
Execution/Result:
The query is giving me the output in terms of documents where the
value 2 and given range is present. Based on current implementation,
I need to iterate through each doc found, get all the value field
(matching input value=2) and then again impose an IF condition for
the range and increment a counter everytime the IF is executed.
This is OK but I am looking for a shorter method.
A. Is it possible that on firing first query, I get the count of
occurence itself. I think .search always returns number of docs.
B. If this is not possible, is it possible that having obtained the
document in which the given input might be present, again execute a
query on that document itself and find the occurence of given input
for the given time range.
C. I tried with putting a count of occurence of given value during
the indexing phase in index itself. But since TIME CROSSOVER can also
happen inside the same file, the count which is stored during the
indexing process is not proper. Hence I don't think I can store the
count of the occurence during the indexing phase itself.
Please assist. Let me know if any point is not clear and I will
clarify it again.
