Abstract: A method performed by one or more processing devices includes receiving, from a client device controlled by a user, a search query including one or more search terms and user information of the user; accessing, by a server device based on receipt of the search query, a private content index for indexing private content of users; wherein the private content index includes access control lists; identifying, based on a comparison of the access control lists to the user information received, private content that is accessible to the user; identifying private content that is responsive to the one or more search terms and that is accessible to the user; identifying, based on a search of public content by the server device, public content that is responsive to the one or more search terms; and sending, to the client device, search results for the identified private and public content.

Abstract: An efficient information search mechanism provides control over the relaxation of a search query to users that are requesting searches. Through such a mechanism, a user can specify a sequence of sub-queries that is associated with variations of the main search criteria, and specify a progression in which to execute the sub-queries. Hence, users can impart their priorities with respect to search term variations used in relaxing the main search criteria, which further allows the users to impart their notion of the relevance of results that may be returned by particular sub-queries. A query that includes a sequence of sub-queries is received and the sub-queries are executed, if at all, by a database server in an order based on the progression specified by the user. Response time and network loading are improved through reduction of unnecessary work by the database server and through reduction of computationally costly communications between client and server and associated processing.

Abstract: Systems, methods, computer-readable media and other embodiments are provided for automatically determining a language of a document from a set of candidate languages. In one embodiment, a system includes a logic for setting an assumption value associated with each of the languages of the set of candidate languages where the assumption value indicates that the document is not in the language. A language analyzer determines the language and generates an output that indicates that the document is one language of the candidate languages when the assumption value for the one language passes a threshold value.

Abstract: Example, systems, methods, computer media, and other embodiments for determining relevance rankings for pages identified in a search query is provided. In one example, a computer program product can be configured to identify a candidate set of pages in response to a search query. A content-based relevance rank can be determined for at least one page of the candidate set of pages based on a content of the at least one page. The content-based relevance rank can be adjusted for one or more selected pages from the candidate set of pages by distributing a relevance rank from one or more pages that point to the one or more selected pages.
