Advanced search enables searching specific fields for any terms. You can separate search terms with spaces or you can search for exact phrases by enclosing the phrase in quotes (e.g. "Puerto Rico").
If you enter search terms into multiple fields, it will return profiles that are correct for all of those parameters (i.e. it assigns an AND function between fields).
Wildcard characters are supported at the beginnings and ends of search terms. To use them, place an asterisk ("*") sign before and/or after a whole or partial search term. This construct will match your term plus any number of arbitrary characters before and/or after. Examples: scien* matches science, scientist, scientific, etc.
Because we have added new fields to the member profiles, you have the option to search by some of the "old" parameters and the option to search by some of the "new" parameters. Because not all users have added geographic information the map might only display a portion of all results.
