The search process has been greatly simplified throughout the years. A user enters one or several words. The system finds the names of files where the words appear. If the user supplies a combination of words, the system can find them individually or in some type of semantic relationship as in Boolean, or logic, operations. It is possible to ask the equivalent of “I want documents that discuss giraffes in Costa Rica”.
Indexing files form a representation system, a system representing the information in a collection of documents, a computer-based bibliographic representation. But there are other bibliographic representations. Document titles and other types of summaries are good examples of representation systems as well.
The reader will notice that each type of representation provides their own set of mutual semantic relationships, degree of specificity, and other attributes that correspond to their particular interpretations of the original information.
