Enable Enhanced Lookups Enable enhanced lookups so users can use wildcards in their lookups and sort, filter, and page through their results. Enhanced lookups are available for the Business Account, Contact, Custom Object, Opportunity, Person Account, User, Work Order, and Work Order Line Item objects.
Specify Lookup Search Filter Fields After enabling enhanced lookups, specify which fields users can use to filter lookup search results. If you don't specify any fields, your users can't use filters in enhanced lookup dialogs.
Enable Lookup Auto-Completion Enable lookup auto-completion so users can select items from a dynamic list of matching, recently used records when editing a lookup field. It’s supported for account, contact, user, opportunity, and custom object lookups.
