mongodb
package!Release Notes
Experimental Support for Queryable Encryption Text Field Prefix, Suffix and Substring Queries
Important
Substring, prefix and suffix search are in preview and should be used for experimental workloads only. These features are unstable and their security is not guaranteed until released as Generally Available (GA). The GA version of these features may not be backwards compatible with the preview version.
When using Queryable Encryption with both automatic encryption and explicit encryption, text fields can now be queried using prefix, suffix and substring queries. This feature requires

. Thelimit

when both options were equal, to avoid leaving cursors open.Clients no longer send a ping on connect
When authentication is enabled, the
