= Configuring {brandname} to index caches
Enable indexing in your cache configuration and specify which entities {brandname} should include when creating indexes.

You should always configure {brandname} to index caches when using queries.
Indexing provides a significant performance boost to your queries, allowing you to get faster insights into your data.

.Procedure

. Enable indexing in your cache configuration.

[source,xml,options="nowrap",subs=attributes+]

include::xml/indexing_enable.xml[]

[TIP]
====
Adding an `indexing` element to your configuration enables indexing without the need to include the `enabled=true` attribute.

For remote caches adding this element also implicitly configures encoding as ProtoStream.
====
+
. Specify the entities to index with the `indexed-entity` element.

== Protobuf messages

* Specify the message declared in the schema as the value of the `indexed-entity` element, for example:
+
[source,xml,options="nowrap",subs=attributes+]
----
include::xml/indexing_entities_pojo.xml[]
----
+
This configuration indexes the `Book` message in a schema with the `book_sample` package name.

== Java objects

* Specify the fully qualified name (FQN) of each class that includes the `@Indexed` annotation.
