Section Searching Example: Creating HTML Sections

4.3 Section Searching Example: Creating HTML Sections

When documents have internal structure such as in HTML and XML, you can define document sections by using embedded tags before you index. This approach enables you to query within the sections by using the WITHIN operator. You define sections as part of a section group.

This example defines a section group called htmgroup of type HTML_SECTION_GROUP. It then creates a zone section in htmgroup called heading identified by the <H1> tag:

begin
ctx_ddl.create_section_group('htmgroup', 'HTML_SECTION_GROUP');
ctx_ddl.add_zone_section('htmgroup', 'heading', 'H1');
end;
