Abstract: Searching data for a user includes searching a first set of data that is directly accessible to the user to provide a first set of search results, searching a second set of data that is not directly accessible to the user to provide a second set of search results, comparing the search results, and, if at least a portion of the second set of search results is better than the first set of search results, causing the portion to be provided to the user. Causing the portion to be provided to the user may include obtaining permission from an entity that controls permissions to the portion of the second set. The entity that controls permissions to the portion of the second set may be an owner of the portion. The first set of data may be determined based on credentials and sharing permissions of the user.

Abstract: Providing incremental search suggestions as a user enters terms in a search query includes determining if a recently entered term is in a context-free dictionary of natural language phrases, generating natural language query search completion candidates corresponding to terms provided by the user in the search query if the recently entered term is in the context free dictionary, determining if the recently entered term contains a keyword hint if the recently entered term is not in the context free dictionary, generating keyword search completion candidates if the recently entered term is at least part of a keyword hint, scoring the candidates from a current iteration and any previous iterations from previously entered terms to provide a set of possible candidates, and ordering the possible candidates based on at least the scoring. Providing incremental search suggestions may also include building compound search queries that include natural language phrases and keywords.
