Embodiments are directed towards managing mobile searches by enabling a user to indicate a context of a search query to narrow a scope of the search. A user may fine tune a search by selecting from a plurality of pre-defined contexts for which to perform a search query. In one embodiment, the user may combine two or more pre-defined contexts to create more complex contexts for use in customized context search queries. The user also enters one or more search terms. A subset of databases is selected from a plurality of databases associated with different subject categories. The subset of databases is selected as predefined by an operator based on the user's context, and searched based on the user's entered search terms and selected context. Results are then aggregated and provided to the user. Results may be rank ordered based on the given user context or user's previous search behavior.
