Administrators and developers often need to customise the Search Layout for both standard and custom objects within their Salesforce orgs. 

Customising a Search Layout allows users to select the standard and custom fields that are displayed when records from that object appear in various places around Salesforce. Such as when returned in a search, displayed in a lookup dialog or on the recently viewed records list displayed on the tab home page.

To customise a Search Layout, locate the object in the Setup menu within Salesforce and select the Search Layouts menu item:

Now make the customisation. In this example, the Accounts Identity User Search Layout has been edited to have an additional field, the Billing Street.

Now when the org is compared either to another org or to source control, Gearset will highlight that the Account object has changed.

Deploying the Account object will deploy the Search Layout change. 

Note: It is normal to find the custom object present twice in the comparison results when looking in the All items tab - once as Different, including this change, and once as No different.
