An index-see-also element within an indexterm redirects the reader to another index entry that the reader should reference in addition to the current one.
The index-see and index-see-also elements allow a form of redirection to another index entry within the generated index. The index-see element refers to an index entry that the reader should use instead of the current one, whereas the index-see-also element refers to an index entry that the reader should use in addition to the current one.
Processors should ignore index-see and index-see-also elements if their parent indexterm element contains any indexterm children.
In addition to its "see also" redirection, an index-see-also functions as a pointwise index term, thereby typically generating a page reference as well as the "see also" indication.
It is not an error for there to be multiple index-see-also elements for a single index entry.

The following example illustrates the use of an index-see-also redirection element within an indexterm:
<indexterm>Carp <index-see-also>Goldfish</index-see-also> </indexterm>
- Carp, 56
- see also Goldfish
The following example illustrates the use of an index-see-also redirection element to a more complex (multilevel) indexterm:
<indexterm>Feeding <index-see-also>Goldfish <indexterm>feeding</indexterm></index-see-also> </indexterm>
This is part of the indexing markup that might generate index entries such as:
- Feeding, 348
- see also Goldfish feeding
- feeding, 56
- flushing, 128, 345
