Myphoner has a powerful search built in. You access it through the search bar at the top-left of your screen. Either by clicking the search field or by hitting the "S" key on your keyboard. Once you start typing, Myphoner will display all matching leads. You can type the beginning of a phone number, name, company name, or any other datapoint you have about the lead.
Notes and tips for using the search
The search will find leads where the phone number starts with what you are typing, but not ending with, so if the phone number is 123456, and you search for "123", it will be found, but if you search for "456", it will not.
The search will normalize input that looks like a phone number, so searching for "+1 123" should be equivalent to searching for "123", but if you see no result, try searching for the same format as you have in your original data.
The search will only display leads from lists that the user performing the search is assigned to. If a user is assigned to a segment, but not the underlying list, leads from that segment will not be searchable (see below for a solution).
How to allow agents to search all leads in the account
If you want agents to be able to search leads that are on lists not assigned to them, you can do this by following the instructions below:
Manage > Settings > Workflow >
Under Search, click the box next to Search all leads
Click Save.
