摘要： An information retrieval system uses phrases to index, retrieve, organize and describe documents. Phrases are extracted from the document collection. Documents are the indexed according to their included phrases, using phrase posting lists. The phrase posting lists are stored in an cluster of index servers. The phrase posting lists can be tiered into groups, and sharded into partitions. Phrases in a query are identified based on possible phrasifications. A query schedule based on the phrases is created from the phrases, and then optimized to reduce query processing and communication costs. The execution of the query schedule is managed to further reduce or eliminate query processing operations at various ones of the index servers.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying points-of-interest. In one aspect, a method includes identifying points-of-interest (POIs) associated with one or more of multiple, selected geographic areas, and determining, for each of the multiple geographic areas, a score associated with the identified POIs. The actions also include generating a combined score for each identified POI based on the determined scores associated with the respective POI, selecting a subset of the identified POIs based at least on the combined scores, and displaying a link to the POIs in the subset.
