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 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: A multi-user search system with methodology for instant indexing. In one embodiment, for example, a system for instant indexing includes a token store storing sets of tokens for current versions of documents. The system further includes a tokenizer server configured to tokenize new versions of the documents and to generate sets of tokens for the new versions of the documents, an instant indexer configured to determine tokens to use to index the documents based on identified differences between the sets of tokens for the new versions of the documents and the sets of tokens for the current versions of the documents, and to generate index mutations including the tokens to use to index the documents, an index mutation journal configured to store the generated index mutations in association with timestamps, and an index mutation server configured to provide, to index servers, from the index mutation journal, generated index mutations for the index servers that are associated with timestamps that are newer than specified timestamps.
