    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. The systems and method can further include searching, the first portion of the event log stored at the first index server and determining a payload based on the search results of the first portion of the event logs. Finally, the systems and methods can include applying one or more attribute filters to the payload and sending the filtered payload.

    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.

    Abstract translation: 具有即时索引方法的多用户搜索系统。 在一个实施例中，例如，用于即时索引的系统包括存储用于当前版本的文档的令牌集的令牌存储器。 所述系统还包括令牌化器服务器，其被配置为对所述文档的新版本进行标记，并为所述文档的新版本生成一组令牌，所述即时索引器被配置为基于所述文档的所述组之间的所识别的差异来确定用于对所述文档进行索引的令牌 用于文档的新版本的令牌和用于当前版本的文档的令牌集合，并且生成包括用于索引文档的令牌的索引突变，索引突变日志被配置为将生成的索引突变与 时间戳和索引变异服务器，其被配置为向索引服务器提供索引变异日志，为与指定的时间戳新的时间戳相关联的索引服务器生成索引突变。

    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.
