    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: 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: 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 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.
