摘要： A system for monitoring search performance and user interaction is provided in the form of a utility (300) including a plurality of monitoring components (302), each for dynamic monitoring of an aspect of searching a collection of documents. An analyzer module (303) analyzes the dynamic monitoring and identifies problems or difficulties in the search performance or user interactions. An output (301), which may be in the form of a display interface, provides information regarding the search performance and user interaction including one or more of: reasoning, improvement suggestions, reports, and problem alerts. The analyzer module (302) compares the dynamic monitoring to benchmark search engine conduct and document collection state.

摘要： System for the storage and maintenance of data sets updates in a storage subsystem, that comprises direct access storage device(s) that serves as the main storage of the storage subsystem and on which the data sets are originally stored; a Cache memory storage device that enables fast interaction with the storage subsystem, on which a copy of the data sets is stored; a non-volatile storage device partitioned into a plurality of fixed size non-volatile memory pages. The system employs an update process, in which the changes to the data sets are applied to the data set copy stored on the Cache memory device; a journal of the changes that are being made to the data sets stored on the Cache memory device, utilizing the non-volatile memory pages to store update records reflecting the changes in the data sets; a reconstruction process in which the data sets are reconstructed utilizing the update records stored on the non-volatile memory pages, and the data sets stored on the direct access storage device; and a process for freeing arbitrary non-volatile pages from their prior association with data sets that are stored in the Cache memory.

摘要： A method for searching a document collection includes providing an index of terms indicating the documents in which the terms appear. A first statistical distribution of each of at least some of the terms in the index and a second statistical distribution of each of at least some of the categories are estimated a over the documents in the collection. A query including one or more of the terms and a category restriction referring to at least one of the categories is accepted. A modified term distribution is produced by operating on the first estimated statistical distribution of at least one of the terms in the query using the second estimated statistical distribution of the at least one of the categories, responsively to the category restriction. The query is applied to the index so as to return a response, in which occurrences of the at least one of the terms are scored responsively to the modified term distribution.
