The Order Management user interface lets customer representatives manage orders manually when needed. **Order Management** is available from the Episerver Commerce top menu.
From Order Management you create and modify carts and purchase orders, and access information on customer profiles.
## Extend the search result display
When adding a new line item to a cart or an order, a user finds the correct one by searching for it. If a product has many variants, the system helps the user select the correct one by displaying variant-specific information (for example size or color) for each search hit. However, those properties differ from site to site. The system does a "best guess" by inspecting content types.
If you want more control over what is shown, use the EPiServer.Commerce.Catalog.IEntryInformation interface. By implementing IEntryInformation, and [replacing our default implementation](🔗), you can customize which properties are displayed. The interface has just one method, which returns a dictionary. That dictionary should contain the names of properties to show, as well as a string representation of their value, suitable to be shown to the user.
