{{esql}} dense vector functions [esql-dense-vector-functions]

:::{tip} For more examples of these functions in action, refer to the {{esql}} for search tutorial. :::

{{esql}} supports dense vector functions for vector similarity calculations and k-nearest neighbor search. Dense vector functions work with dense_vector fields and require appropriate field mappings.
