+When connection identity verification is not required or needs to be explicitly disabled, a `DisableIdentity` configuration option exists.
+Initially there was a typo and the option was named `DisableIndentity` instead of `DisableIdentity`. The misspelled option is marked as Deprecated and will be removed in V10 of this library.
+Although both options will work at the moment, the correct option is `DisableIdentity`. The deprecated option will be removed in V10 of this library, so please use the correct option name to avoid any issues.

+#### Redis-Search Default Dialect
 
-Please see [out contributing guidelines](CONTRIBUTING.md) to help us improve this library!
+In the Redis-Search module, **the default dialect is 2**. If needed, you can explicitly specify a different dialect using the appropriate configuration in your queries.
+
+**Important**: Be aware that the query dialect may impact the results returned. If needed, you can revert to a different dialect version by passing the desired dialect in the arguments of the command you want to execute.
+For example:
+```
+	res2, err := rdb.FTSearchWithArgs(ctx,
+		"idx:bicycle",
+		"@pickup_zone:[CONTAINS $bike]",
+		&redis.FTSearchOptions{
+			Params: map[string]interface{}{
+				"bike": "POINT(-0.1278 51.5074)",
+			},
+			DialectVersion: 3,
+		},
+	).Result()
+```
+You can find further details in the [query dialect documentation](https://redis.io/docs/latest/develop/interact/search-and-query/advanced-concepts/dialects/).
