Add a new cluster setting `search.allow_expensive_queries` which by default is `true`. If set to `false`, certain queries that have usually slow performance cannot be executed and an error message is returned. - Queries that need to do linear scans to identify matches: - Script queries - Queries that have a high up-front cost: - Fuzzy queries - Regexp queries - Prefix queries (without index_prefixes enabled - Wildcard queries - Range queries on text and keyword fields - Joining queries - HasParent queries - HasChild queries - ParentId queries - Nested queries - Queries on deprecated 6.x geo shapes (using PrefixTree implementation) - Queries that may have a high per-document cost: - Script score queries - Percolate queries Closes: elastic#29050 (cherry picked from commit a8b39ed)
