Simple, Fast Search
If you know the exact name or username of the person you are looking for, you can simply write it in the quick search box on the community's Frontpage.
You can also access the quick search option from any Friends-related page, where you will have an additional option to search only users who have uploaded avatars.
Unlike the Simple Search, the Advanced Search allows the user to create criteria for searching based on the custom profile fields values. Every field that is set as searchable in the custom profile fields configuration will be available in Advanced Search.
