# Combine Parameter

The `Combine` action parameter combines results that:

- derive from the same document.

- contain the same content.

- have the same value in a specific `ReferenceType` field.

By default, the IDOL Content component displays the result with the highest relevance. However, you can use the `Sort` action parameter to set alternative sorting methods.

You can set `Combine` to one of the following options:

-     Simple

-     FieldCheck

-     ReferenceTypeFields
