Abstract: Methods and apparatus related to ranking modifications of a previous query. For example, modifications of a previous query may be generated based on a current query issued subsequent to the previous query by substituting one or more n-grams of the previous query with one or more n-grams of the current query. One or more measures of each of the modifications may be identified and, based on such measures, a ranking of each of the modifications may be determined. One of the modifications may be selected as a submission query based on the rankings of the modifications. The submission query may be selected for submission in lieu of, or in addition to, the current query.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining query results in response to queries. One of the methods includes obtaining first query results that are responsive to a first query; determining that the first query results do not satisfy a requirement; obtaining one or more modified queries for the first query; selecting a modified query from the one or more modified queries; obtaining second query results that are responsive to the selected modified query; analyzing the second query results and the first query results; determining to provide one or more second query results as a result of the analyzing; and providing the one or more second query results.
