is there a documentation for implementing automatic slicing at the search end? like we have in the re-index API documentation.
Why would slicing apply to searching? Searches by default are fanned out to the shards they are querying so there is already parallelism built in. What is the problem you are trying to solve? Are you looking to return large amounts of data through deep paging?
Which version of Elasticsearch are you using?
currently I am using 7.17 and upgrading my app to 8.14, I was thinking to improve the performance of search query.
currently we are using Scroll API | Elasticsearch Guide [7.17] | Elastic
Gentle reminder please.
