|  What
are topical or subject directories?
With topical or subject directories, people have visited and evaluated
the content before adding it into the searchable database. They
also select words and phrases to describe the sites that they add.
Information is usually placed in the engine in a hierarchical fashion
beginning with broad topics then narrowing it down to specific information.
Because there is an evaluation process, more control of the content
has been used before that information was added into the searchable
database. The results of a search may be highly relevant, but not
as current as with indexed database (keyword) engines due to time
required by the reviewers.
Since there is more control over the content added to the searchable
database due to the review process, this type of search engine is
more beneficial to elementary students.
