Hi Ashish,
there is no direct way to just get a search result count based on the time slice. But you can use
_total API that allows filtering conditions and a filter by
createdTime, for example:
filter=lt(entity.createdTime, '1428309071535')
This way you can get a count of entities created before certain point in time, this way
capturing the record count based on timestamp.
Hope this helps.
