Marios Trivyzas dac720d7a1 Add a cluster setting to disallow expensive queries (#51385) (#52279) ... 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: #29050 (cherry picked from commit a8b39ed842c7770bd9275958c9f747502fd9a3ea)		2020-02-12 22:56:14 +01:00
