Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating real-time search results. In one aspect, a method includes receiving a search query from a client; determining that real time search results should be included in a user interface document responsive to the search query; generating the user interface document, including client software to cause the client to present real time search results for the query; and sending the user interface document to the client.

Abstract: A multiversioned position-space indexing system is disclosed. The system includes data structures for maintaining a multiversioned position space including a multi-versioned filter merge list which represents many versions of a changing position space in a very compact form and a position shift map which describes how to translate stored positions in many different log-structured merge tree layers into logical positions at a particular timestamp. Each log-structured merge tree layer can be divided into two sublayers: a final sublayer and a correction sublayer. The final sublayer contains index entries added after the layer's start timestamp and remain live as of the layer's final timestamp as well as deletion makers for index entries that were inserted before the layer's start timestamp, but deleted before the layer's final timestamp. The correction layer contains index entries that were both created and deleted between the start and end timestamps of the layer.

Abstract: A computer system including instructions stored on a computer-readable medium, may include a query manager configured to manage a query corpus including at least one predictive query, and a document manager configured to receive a plurality of documents from at least one document source, and configured to manage a document corpus including at least one document obtained from the at least one document source. The computer system also may include a predictive result manager configured to associate the at least one document with the at least one predictive query to obtain a predictive search result, and configured to update a predictive cache using the predictive search result, and may include a search engine configured to access the predictive cache to associate a received query with the predictive search result, and configured to provide the predictive search result as a search result of the received query, the search result including the at least one document.
