Abstract
Methods, systems, and apparatus, including computer program products, for generating or using augmentation queries. In one aspect, a set of phrase terms of a phrase are received in first ordinal positions, and a set of first hashes for each of the phrase terms. Concatenated hashes from the set of first hashes are generated. Hashes of content terms for received content are compared to the concatenated hashes to determine if a phrase is detected in the content.
