Here is the problem:
- Single Large index with upto 200 million documents
- Each document contains field using epoch timestamp format (padding
is required when creating range requests)
- One of the frequently used search query, a range request on the
timestamp field (10 digits)
- Other searches are fine, but the search using range request
(1207190000 to 1207190258), even small result set, still slow when
"sort" is requested
My questions:
- Is Lucene sorting then search or is it doing search then sort the
results?
- Is there a way to get this type of searches to return faster with
heavier weight on the timestamp not on relevancy?
Any insight would be greatly appreciated
/Regards
