    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: Electronic mail message processing includes: obtaining a set of keywords associated with an electronic mail message; updating, based at least in part on the set of keywords, a set of inverted index records stored in a level 1 cache; determining whether size of the set of inverted index records stored in the level 1 cache exceeds a first preset threshold value; in the event that the first preset threshold value is exceeded, transferring the set of inverted index records in the level 1 cache to a level 2 cache; determining whether size of a level 2 cache file exceeds a second preset threshold value; in the event that the second preset threshold value is exceeded, transferring, according to a path file, inverted index records in the level 2 cache file to a level 3 cache storing a set of inverted index files.

    Abstract: A method and system are provided for identifying type-ahead candidates. A method includes determining a context of past non-threaded emails of a user. The method further includes generating a context index associating the past non-threaded emails of the determined context with repeatable values within the past non-threaded emails. The method further includes receiving characters in a current email and determining a context of the current email. The method further includes determining matches between the current email and the past non-threaded in the context index. The method further includes identifying the corresponding repeatable values and matching the identified corresponding repeatable values with the received characters. The method further includes presenting the candidate words to the user for inclusion in the current email.

    Abstract: Technology is disclosed for a multi-tiered querying system to target queries to systems storing data relevant to the query. A multi-tiered targeted query system comprises at least three tiers: a web tier, an aggregator tier, and a shards tier. Servers at the web tier can be configured to service user data requests and pass them to servers at the aggregator tier. Servers at the aggregator tier can be configured to determine which selected shard servers have the requested information; formulate queries for the selected shard servers; send the queries to the selected shard servers; and aggregate results from the selected shard servers. Servers at the shard tier can be configured to store data, receive queries on that data, and return results for received queries.

    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.
