 Besides basic filtering and aggregation, OpenSearch SQL also supports complex queries, such as querying semi-structured data, JOINs, set operations, sub-queries etc. Beyond the standard functions, OpenSearch functions are provided for better analytics and visualization. Please check our [documentation](#documentation) for more details.
 
-Recently we have been actively improving our query engine primarily for better correctness and extensibility. Behind the scene, the new enhanced engine has already supported both SQL and Piped Processing Language. Please find more details in [SQL Engine V2 - Release Notes](/docs/dev/NewSQLEngine.md).
