UsersWP Advanced Search Addon GPL Overview:

Advanced Search Settings

• It is very easy to add new custom fields as filters to the advanced search form.
• Every new custom field created, has a checkbox to enable the field as an advanced search filter for users.
• For example, if you create a Field Gender and add it as an advanced search filter, you will be able to search only Male Users or Female Users or Transgender or Gender-neutral Users, and so on.
• You can do the same with Country, Age range, Profession, Relationship status, City of Residence, Date, or Place of Birth.
• You can also combine filters for a more granular search. For example, you could search for Female users, from the United States, living in Mexico, in the age range 20 – 30.
• These are just examples, but the possibilities are really endless.
• This add/on is a must for any kind of Users Directory.
