The "Searcher" allows you to filter leads and companies based on several criteria, such as job titles, seniority, location, company size, etc...
Similarly, you can also exclude leads based on the same criteria in case you want to remove some titles, seniorities, locations, company sizes, etc... The few exceptions that don’t have the exclusion option are: person name, company founded, company ownerships, events and # employees.
You can exclude keywords in the different filters by clicking to view "more".
The field "Exclude" will then appear.
Note: You can insert as many person titles as you wish, the searcher will exclude all the criteria you selected in all categories simultaneously.
