Abstract: Techniques are described herein for using user-defined aggregate functions for updating inverted index tables. A user-defined aggregate function is registered in a database system for updating an index table based on changes stored in a staging table. A query specifying the user-defined aggregate function may be executed in parallel to parallelize the updating of the index table.

Abstract: A search system can maintain a search index of metadata and text for objects in a repository, repositories or distributed across a network. The search index can be divided into partitions with a partition assigned a first capacity utilization threshold and a second capacity utilization threshold. If the capacity utilization of the partition is below the first threshold, the system can add, update and delete information in the partition. If the capacity utilization of the partition is above the first threshold, the system can update and delete information in the partition, but cannot add information for new objects to the partition. If the capacity utilization of the partition is above the second threshold, the system can enter a rebalancing mode in which it seeks to rebalance capacity utilization between partitions. The behavior of the system can change depending upon the size of a partition relative to its configurable thresholds.

Abstract: A method, system, and computer program product for information retrieval and sentiment assessment. The method parses a sentiment-aware query to isolate one or more lexical terms to be included in a lexical retrieval of documents containing the lexical terms. The parsing of the query includes parsing the query to isolate portions of the query to be included in the configuration of a sentiment analysis of the retrieved documents. The documents retrieved based on the lexical terms are processed so as to generate a sentiment assessment, and the sentiment found in the retrieved documents might be correlated to terms that are not present in the lexical terms. The sentiment assessment is presented as a “positive” or “negative” indication, or as a sentiment assessment score. The sentiment portion of the query can specify an area of interest, and/or can specify a user-selected classifier model that is used to process the retrieved documents.
