The revolution to metadata from traditional methods of collection management presents a
challenge to information mangers globally. Simpler schemes for metadata need to be
introduced to organize digital information as opposed to complicated ones which also pose
difficulties to end-user searching digital information. These can be listed as follows.
Selecting source: end-users have difficulty in choosing from the many Internet search
engines and in keeping up with the features they offer.
Formulating queries: people have difficulty in expressing their information needs in the
syntax appropriate to the search system they are using. They use only a few words in
their search strategies, often even misspelling them. They are reluctant to explore the
more sophisticated features many search systems offer, such as phrase and name
searching.
Examining results: they accept that a significant number of the hits they do get will be
irrelevant, because their strategies are matched against the whole of the Internet and
the ambiguities in their search strategies produce noisy search results
