A well-known problem for web search is targeting search on information
that satisfies users' information needs. User queries tend to be
short, and hence often ambiguous, which can lead to inappropriate
results from general-purpose search engines. This has led to a number
of methods for narrowing queries by adding information. This paper
presents an alternative approach that aims to improve query results by
using knowledge of a user's current activities to select search
engines relevant to their information needs, exploiting the
proliferation of high-quality special-purpose search services. The
paper introduces the PRISM source selection system and describes its
approach. It then describes two initial experiments testing the
