a little error about SearchType

elasticsearch/core/src/main/java/org/elasticsearch/action/search/TransportSearchAction.java

Line 287 in b727a60

searchRequest.searchType(QUERY_THEN_FETCH);

when it comes to one shard , here should be “QUERY_AND_FETCH”, not QUERY_THEN_FETCH.

@kkewwei Thanks for reporting this. QUERY_AND_FETCH was deprecated in 5.x, but I think we need to adjust the comment here.

Check out #22996 and #28098 where this was changed. We moved the optimization for the single shard case to SearchService. I think what we have now is fine.
