Query modification

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for query modification. In one aspect, a method includes receiving an original query including a first limitation. First search results responsive to a modified query are obtained, where the first limitation has been omitted from the modified query. One or more common characteristics shared by two or more resources are identified. Each of the two or more resources corresponds to a different highly-ranked result of the first search results. A second modified query including the original query and a second limitation representing the one or more common characteristics is generated. Second search results responsive to the second modified query are obtained. The second search results are provided in a response to the original query.

主权项

1. A computer-implemented method, comprising:
receiving an original query including a first limitation that constrains a search; modifying the original query to obtain a modified query in which the first limitation that constrains the search has been omitted; obtaining, from a search engine system, first search results responsive to the modified query, wherein the first search results have an associated ranking determined by the search engine system, and wherein each of the first search results refers to a respective resource; identifying one or more common characteristics shared by two or more resources, each of the two or more resources corresponding to a different highly-ranked result of the first search results; generating a second modified query comprising the original query and a second limitation representing the one or more common characteristics, the second limitation requiring results responsive to the second modified query to reference a resource having the one or more common characteristics; obtaining second search results responsive to the second modified query, wherein each of the second search results refers to a resource having the one or more common characteristics; and providing the second search results in a response to the original query.
