…ect#13788) This introduces a basic "approximation" framework that improves query performance by modifying the query in a way that should be functionally equivalent. To start, we can reduce the bounds of a range query in order to satisfy the `track_total_hits` value (which defaults to 10,000). --------- Signed-off-by: Harsha Vamsi Kalluri <harshavamsi096@gmail.com> Signed-off-by: Michael Froh <froh@amazon.com> Co-authored-by: Michael Froh <froh@amazon.com>

Description
Most of the logic is as per #13566. I've introduced a new
ApproximateableQuerythat is virtually similar to whatIndexOrDocValuesdoes today. It returns either anoriginalQueryor anapproximateQuery. During search time we evaluate if a query matches a particular requirement for it to be rewritten fromoriginalQuerytoapproximateQuery. Here I started off with just converting theDateRangeQueryto use the approximation. If we have a top level range query on a date field, we will approximate the results by only scoring10K or size.Related Issues
