Abstract
A tag database storing tags indexing captured object can be searched efficiently. In one embodiment, such a search begins by receiving a query for one or more objects captured by a capture system, and determining whether a query time range exceeds a time range of a set of fast tables. In one embodiment, the invention further includes searching the set of fast tables if the query time range does not exceed the time range of the fast tables, the set of fast tables containing tags having meta-data related to captured objects. In one embodiment, the invention further includes searching a set of hourly tables if the query time range does exceed the time range of the fast tables. In one embodiment, the present invention further includes searching a set of daily tables if the query time range also exceeds the time range of the hourly tables.
