Clustered search indexing for correlated data groups

Abstract

Systems, methods and devices described herein enable producing and utilizing a clustered search index as a way of searching correlated data groups, such as channel lineups. In particular, in some implementations systems, methods and devices are operable to create a clustered search index that includes clusters of TV channels frequently provided together in various channel lineups in order to improve searching efficiency. That is, the resultant search index is based on sub-lineups of channels that are shared by multiple channel lineups (i.e. sub-lineup indexing). Each sub-lineup includes channels that are frequently provided together, as determined by analysis of the channel lineups offered by the various providers. Additionally and/or alternatively, in some implementations systems, methods and devices are operable to process a search query by selecting a number of pertinent channel clusters from a clustered search index associated with one or more characteristics associated with the query.
