The deleted counter is incremented even if the document is missing. Also, this commit ensures that the scroll id is cleared even if no documents are found by the scan request.
this is really just a workaround for plugins to run their own
REST tests instead of the core ones. It opts out of the rest test
loading from the core jar file and tries to load from the classpath instead.
Eventually we need to fix this infrastrucutre to move away from parameterized
tests such that subclasses can override behavior.
Closes#11721
The delete by query plugin adds support for deleting all of the documents (from one or more indices) which match the specified query. It is a replacement for the problematic delete-by-query functionality which has been removed from Elasticsearch core in 2.0. Internally, it uses the Scan/Scroll and Bulk APIs to delete documents in an efficient and safe manner. It is slower than the old delete-by-query functionality, but fixes the problems with the previous implementation.
Closes#7052
