Description
With #8391 we skip search_after short cutting in case of missing is specified, but actually no matter user specifies missing in request or not, the default missing value is
_last. This PR takes missing value into consideration of search_after query optimization, for example, if we sort result in asc order and even though min/max value is out of range, the target shard can match in case of missing value is larger than search_after value.Related Issues
