Collaborative search generally uses previously collected search sessions as a resource to help future
users to improve their searching by query modification. The recommendation or automatic extension of
the query is generally based on the content of the old sessions, or purely the sequence/order of queries/
texts in a session, or a combination. However, users with the same expressed query may need different
information. The difference may not be topic related. This chapter proposes to enrich the context of
query representation to incorporate non-topical properties of user information needs, which the authors
believe will improve the results of collaborative search.

by the investigator. This chapter will research the
problem of storing in compact form those moves
and judgments so that later investigators may ex-
ploit them to speed and increase the effectiveness
of their own research.
Anyone who puts down a task, and resumes it
some time later makes use of the associating pow-
ers of the brain, and of various support systems,
to get the human mind back in context. The same
individual, even when working with the same set
of data, might have several possible contexts, and,
indeed might have several contexts simultaneously
latent in mind while scanning or browsing. We know
that the human mind is superb at this scanning and
In support of collaboration among individuals whose
work involves exploration of data networks (such
as the World Wide Web, or sets of intelligence in-
formation, or more detailed databases of scientific
information), some researchers are examining a
problem that I will call “quest reuse”. The central
idea is that a person doing such research is on a quest
that has specific goals. Those goals are reflected
in the search moves and value judgments made
