- Index overview
DITA provides several elements to enable indexing. Whether and how an index is rendered will vary based on implementation decisions and rendering formats.
- Index elements
The contents of <indexterm> elements provides the text for the entries in an index. <indexterm> elements can be nested to create additional levels of indexing, such as secondary and tertiary index entries.
- Location of indexterm elements
<indexterm> elements can occur in topic prologs, anywhere else in DITA topics, and in DITA maps.
- Index locators
An <indexterm> element binds the content of the element, typically a term or subject, to a specific location in a document.
- Index redirection
The <index-see> and <index-see-also> elements enable redirection to other index entries within a generated index.
- Index ranges
Authors can use the @start and @end attributes on a pair of <indexterm> elements to index an extended discussion. The generated index entry reflects the span between the two <indexterm> elements .
- Index sorting
The combination of an <indexterm> and a <sort-as> element specifies a sort phrase under which an index entry is grouped or sorted.
- Examples of indexing
This section contains examples and scenarios that illustrate the use and processing of indexing elements.
