…tled searches (elastic#42510)" This reverts commit dd1ce50.
This commit adds a function in NodeClient that allows to track the progress of a search request locally. Progress is tracked through a SearchProgressListener that exposes query and fetch responses as well as partial and final reduces. This new method can be used by modules/plugins inside a node in order to track the progress of a local search request. Relates elastic#49091

There was a problem hiding this comment.
I would make these methods static and rename them to buildSearchShards

There was a problem hiding this comment.
I have opened #53373 to address these comments I left last week (besides the one on concurrency that I need to have a closer look at), plus a few other things.

This commit adds a function in NodeClient that allows to track the progress
of a search request locally. Progress is tracked through a SearchProgressListener
that exposes query and fetch responses as well as partial and final reduces.
This new method can be used by modules/plugins inside a node in order to track the
progress of a local search request.
Notes for reviewer:
We cannot track the progress efficiently if the request is splitted into read-only and write indices.
This optimization is also not effective since it doesn't protect against the lost of a context if read-only indices are slow to answer, hence the revert.
This is needed to add the search progress listener in the main SearchTask.
