Abstract: A multi-user search system with methodology for personal searching. In one embodiment, for example, a system for personal searching includes a plurality of index servers storing a plurality of index shards. Each index shard of the plurality of index shards indexes a plurality of documents. Each document of the plurality of documents belongs to one of a plurality of document namespaces assigned to the index shard. The system further includes a front-end server computer for receiving a search query from an authenticated user; an access control server for determining an authorized document namespace the authenticated user is authorized to access; and a query processor for answering the search query and restricting, based on an identifier of the authorized document namespace, an answer to the search query to identifying only documents satisfying the search query and belonging to the authorized document namespace.

Abstract: Enable using a user computer to search the user's personal content items hosted by an online content management service, the online content management service having an indexer computer configured to generate a base index of the user's content items hosted by the service, a base index server computer configured to transmit the generated base index over a network to the user computer, an index mutation generator computer configured to generate index mutations for subsequent changes to user's hosted content items, and an index mutation sever computer configured to transmit the generated index mutations over the network to the user computer. In one aspect, the system and method enable searches of the user's hosted content items and changes thereto to be conducted at the user computer using an index local to the user computer constructed based on the base index and the index mutations received by the user computer.

Abstract: A method and system for facilitating online payments are disclosed. According to one aspect of the present invention, a payment agreement is established at a payment service provider that defines terms of a payment relationship between a merchant and a user. The establishing of the payment agreement includes linking the payment agreement with a payment account of the merchant or user stored at the payment service provider. After establishing the payment agreement, a payment request associated with a transaction is received, whereby the payment request includes a unique identifier to identify the payment agreement stored at the payment service provider. Based on a verification that the payment request complies with terms of the payment agreement, the payment request is processed.

Abstract: Techniques for proactively sending hosted content items to user computing devices. In one embodiment, for example, a method includes collecting access event data representing a plurality of access events pertaining to a content item hosted with an online content management service; based on the access event data indicating that the content item is accessed at a plurality of user computing devices, determining a cross-device access signal for the content item; collecting additional access event data representing a third access event pertaining to the content item; and based on the additional access event data satisfying the cross-device access signal, sending at least a portion of the content item to a user computing device of the plurality of user computing devices.

Abstract: A system and method for proactively sending hosted content items to user computing devices. In one implementation, an online content management system collects access event data representing a plurality of access events pertaining a plurality of hosted content items. The system determines a cross-device access signal for a first hosted content item. The system then detects a first access event pertaining to the first hosted content item. Thereafter, the system determines whether the first access event matches the cross-device access signal. If the first access event matches the cross-device access signal, then the system sends a second hosted content item to a user computing device. The second hosted content item can be the first hosted content item. Alternatively, the second hosted content item can be a content item that is related to the first hosted content item according to the access event data.

Abstract: Multi-user computer search system with methodology for bypassing instant indexing of documents. In some embodiments, for example, a system for bypassing instant indexing includes a token store storing a set of token for a current version of a document and a tokenizer server configured to tokenize a new version of the document and to generate a set of tokens for the new version of the document.

Abstract: Disclosed are systems and methods of querying a hybrid event index of a user. The systems and methods can include receiving a search request pertaining to at least a first namespace of a plurality of namespaces and determining a first index server storing a first portion of the hybrid event index associated with the first namespace. The systems and methods can further include searching, the first portion of the hybrid event index stored at the first index server, determining one or more attributes from the search request, and determining a payload based on the search results of the first portion of the hybrid event index. Finally, the systems and methods can include applying one or more attributes to the payload and sending the filtered payload.

Abstract: Disclosed are systems and methods of querying an event log of a user. The systems and methods can include receiving a search request pertaining to at least a first namespace of a plurality of namespaces and determining a first index server storing a first portion of the event log associated with the first namespace, the first index server being one of a plurality of index servers, each of the plurality of index servers storing a portion of the event log pertaining to at least one namespace of the plurality of namespaces.
