For documents that have internal structure, such as HTML and XML, you can define and index document sections. By indexing document sections, you can narrow the scope of your queries to predefined sections. For example, you can specify a query to find all documents that contain the term dog within a section defined as Headings.

Before indexing, you must define sections and specify them with the section group preference.

Oracle Text provides section groups with system-defined section definitions for HTML and XML. You can also specify that the system automatically create sections from XML documents during indexing.
