Tags and Keywords

Hello,

How does one enable users to search with multiple terms to locate other users easier?

Example :

User1 = apple orange pear

User2 = apple peach pear

User3 = apple plum peach

If a user searches Apple, everyone comes up... If a user searches pear only 1 and 2 come up ... however if they search apple pear no one comes up at all when there are two users that fit the search request. Thanks for your time!

If the user has these keywords in the tag, they will come up when searched by tag.
