# EvaluationOptions

Learn how to configure a query evaluation.

This immutable class configures a call to [`evaluate`](/reference/sdk/php/api/core/plug/evaluate).

Start from [`defaults`](/reference/sdk/php/api/options/evaluation-options/defaults) and chain the `with*` methods to build the options. Each method returns a new instance, leaving the original unchanged.
