    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: 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: A campaign offers and rewards system includes an offer serving engine that provides offers or rewards. An analytics engine, with data intelligence, identifies receipt line items and ties the line items, including uniform price code (“UPC”), stock keeping unit (“SKU”) or product short name from different receipts to create a list of products and services not matched to advertisers. A redemption engine is in communication with a database that includes a reward budget. The redemption engine assists in controlling the redemption of rewards in view of the reward budget and in response to a communication from the analytics engine.

    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. The system further includes an instant indexer server configured to determine tokens to index the document by based on identified differences between the set of tokens for the new version of the document and the set of tokens for the current version of the document, to determine whether the new version of the document is a bypass document version or non-bypass document version, and to generate an index mutation for the new version of the document including a specification of whether the generated index mutation is a bypass index mutation or a non-bypass index mutation based on whether the new version of the document is a bypass document version or non-bypass document version. The system also includes an index mutation server configured to provide the generated index mutation to an index server, if the generated index mutation is a non-bypass index mutation, or not provide the generated index mutation to the index server, if the generated index mutation is a bypass index mutation.

    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.
