A typical search application allows the user to enter a query. The application executes the query and returns a list of documents, usually ranked by relevance, that satisfy the query. The application enables the user to view one or more documents in the returned hitlist.
For example, a application portal might index URLs (HTML files) on the worldwide web and provide query capabilities across the set of indexed URLs. Query hitlists are composed of URLs that the user can visit.
Figure 1-3 illustrates the flowchart of how a user interacts with a simple query application. The figure shows the steps required to enter the query and to view the results. Rectangular boxes indicate application tasks and oval boxes indicate user-tasks.
As shown, the a query application can be modeled according to the following steps:
The rest of this chapter explains how you can accomplish these steps with Oracle Text.
