Class SearchRequestAttributesExtractor

java.lang.Object

org.elasticsearch.action.search.SearchRequestAttributesExtractor

public final class SearchRequestAttributesExtractor
extends Object

Used to introspect a search request and extract metadata from it around the features it uses. Given that the purpose of this class is to extract metrics attributes, it should do its best to extract the minimum set of needed information without hurting performance, and without ever breaking: if something goes wrong around extracting attributes, it should skip extracting them as opposed to failing the search.
