Abstract
Methods, systems, and apparatus, including computer program products, in which a first search query in a session is compared to a second search query within the session to determine whether any terms included in the second search query differ from terms in the first search query. If differing search terms are identified in the second search query, the differing search terms can be excluded from bigram analysis with other search terms included in the second query.
