Abstract :
Given that time is money, Web searching can be a very
expensive proposition. Even with the best search technology,
the usefulness of search results depends on the
searcher’s ability to use that technology effectively. In an
effort to improve this ability, our research investigates
the effects of logic training, interface training, and the
type of search interface on the search process. In a study
with 145 participants, we found that even limited training
in basic Boolean logic improved performance with a simple
search interface. Surprisingly, for users of an interface
that assisted themin forming syntactically correct
Boolean queries, performance was negatively affected
by logic training and unaffected by interface training.
Use of the assisted interface itself, however, resulted in
strong improvements in performance over use of the
simple interface. In addition to being useful for search
engine providers, these findings are important for all
companies that rely heavily on search for critical aspects
of their operations, in that they demonstrate simple
means by which the search experience can be improved
for their employees and customers.
