The Magic of Indexing

Each record or citation in an index or database consists of fields.

When you search by a field, the computer will "look" only in that field when it looks through all the records in the database. It will try to match your search term.

The following examples are commonly found commonly in library catalogs and indexes:
Author Search looks only in the author field
Title Search looks only in the title field
Subject Search looks only in the subject heading field
Date Search looks only in the date field
But . . . a Keyword Search looks for items anywhere in the record. It is the broadest search.
