Abstract
Embodiments are directed towards employing an index of relevant items to determine and provide items that are relevant to a query. A data store that includes a plurality of items may be generated for each user. The user data store may be employed to generate an index of relevant items for each user. Relevant items may be pre-ranked in the index based on a degree of relevancy to a corresponding item. The index of relevant items may be employed to determine ranked relevant items associated with at least one item associated with a query. In response to the query, the relevant items may be further ranked or re-ranked based on at least a current time of the query and a time decay function associated the relevant items. A subset of the determined ranked relevant items may be provided to a client device for display to the user.
