Searching with metadata comprising degree of separation, chat room participation, and geography

Searches can be performed by attaching social contact metadata to a query where the metadata may be related to a degree of separation, chat room participation and geographical information related to an owner's contacts. Searches can then be executed by generalized search engines based at least in part on the metadata. The metadata may include contact identifiers that are unique across one or more social networks, and may include contacts for individual people as well as groups or other affiliations.
