# Components

Some of the PHI entities extract components as well as whole matches. Components are parts of a match that can provide useful information. For example, the entity for an address can return components for the street and postcode.

IMPORTANT: The post-processing script requires components. The default PHI configuration file enables components. If you use a custom configuration file you must set the `EnableComponents` parameter to `True` to return components.

The following sections list the components available for particular entities.

NOTE: The PHI grammars sometimes generate additional components, which it uses to eliminate false positives during post-processing. If you disable post-processing, you might see these additional components. However, Micro Focus recommends that you always enable post-processing for these grammars.
