Claim:
One or more computer-readable media having computer-readable instructions thereon which, when executed by a computer, cause the computer to: receive a physical ID that corresponds to a specific media upon which content resides that can be experienced by a user; attempt to map the physical ID to a logical ID by searching a first table containing physical ID-to-logical ID mappings using a first search, the first search comprising a low cost search; if the first search is unsuccessful, search a second table containing physical ID-to-logical ID mappings using a second search; if the second search is unsuccessful, search the first table using a third search, the third search comprising a higher cost search than the first search; and if a logical ID is found that corresponds to the physical ID, search a database that contains metadata associated with the specific media by using the logical ID as a basis for a search query, wherein different instances of a specific media with the same content thereon are associated with different physical IDs that are mappable to the same logical ID.
