Abstract: Disclosed herein are techniques for combining content management system functionality with an email or messaging server. A system can associate an email with a content item, through express attachment, direct reference such as a link, indirect reference, or otherwise. The system can store the associated content item within content item storage or identify a stored content item that is identical to the content item that is associated with the email. The system can then enhance email service functionality with the stored content item. For example, the system can present the stored content item or information about the stored content item along with the email. The system can also automatically grant permissions to the stored content item with participants of the email.

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 multi-user search system with methodology for personalized search query autocomplete. In one embodiment, for example, a computer-implemented method includes: receiving a search query having an incomplete token; generating an index key that is composed of both (a) an identifier of a document namespace that a user account associated with the search query is authorized to access, and (b) the incomplete token; accessing an index dictionary with the index key to identify a plurality of index tokens, each index token of the plurality of index tokens having the identifier of the document namespace as part of the index token and having the incomplete token as a token portion of the index token or as a prefix of the token portion of the index token; iterating over the plurality of index tokens until a stop condition is reached; and returning an answer to the search query based on the iterating.

Abstract: A multi-user search system with methodology for personalized search query autocomplete. In one embodiment, for example, a method for personalized search query autocomplete includes receiving, from an end-user computing device of an authenticated user, a completion search query including a completion token; determining an identifier of an authorized document namespace the authenticated user is permitted to access; generating an index key including the authorized document namespace identifier as a prefix and the completion token as a suffix; accessing an index dictionary with the index key to identify and iterate over a plurality of prefixed index tokens until a stop condition is reached, each of the plurality of prefixed index tokens including the authorized document namespace identifier as a prefix and the each index token as a suffix, the completion token being a prefix of or matching the each index token; and for each prefixed index token of the plurality of prefixed index tokens, determining whether any documents identified in a postings list associated with the each prefixed index token satisfies the completion query, and returning filenames of any such documents satisfying the completion query in an answer to the completion query.

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 content management system rendering a file sharing GUI on a first device which is communicatively coupled to a content management system and associated with a first user having an account with the content management system. A file to be shared with a second user is identified in response to the file being selected and dragged. In response to the file being identified, a contact section displaying contact icons is rendered. The selected file is released on a displayed contact icon and a user identifier, e.g., an email address or account, associated with the displayed contact icon is identified. In response to the user identifier being identified, the selected file is shared with a second user associated with the user identified.

Abstract: A system and method for enabling a user to use a user computer to search the user's personal content items hosted by an online content management service. In one aspect, the user computer is configured to obtain a search query, use the search query to identify in a local index at the user computer one or more of the user's hosted content items that satisfy the search query, and display, in a graphical user interface at the user computer, a search answer summary for each of the one or more of the user's hosted content items that satisfy the search query.

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 translation: 一种用于主动发送托管内容项到用户计算设备的系统和方法。 在一个实现中，在线内容管理系统收集表示与多个托管内容项有关的多个访问事件的访问事件数据。 系统确定第一托管内容项的跨设备访问信号。 然后，系统检测与第一托管内容项有关的第一访问事件。 此后，系统确定第一访问事件是否与跨设备访问信号匹配。 如果第一访问事件与跨设备访问信号匹配，则系统将第二托管内容项目发送到用户计算设备。 第二个托管的内容项目可以是第一个托管的内容项目。 或者，第二托管内容项目可以是根据访问事件数据与第一托管内容项目相关的内容项目。
