In addition to the various search and filtering options provided in Smart Lists and at the top of the main Leads, Contacts, and Deals pages, Base also offers a Global Search function in the upper right hand side of your account.
Your most recently visited records will appear as soon as you click into the field - if you're looking for something you viewed not too long ago, you'll find it displayed here.
We'll display information to make it easier for you to distinguish similarly named records from each other during a search. For example, you'll see the City and Country displayed right in the search results when you search for a Contact.
Deals will display their current owner to help you distinguish different records as well.
And of course, you can also choose to filter results to just the records that you own to further filter your results.
