<index-see-also>
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>
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:
<ph>
within
<index-see-also>
:<indexterm>μ = E<sub>0</sub>/V<sup>2</sup>
<index-see-also>E=mc<sup>2</sup></index-see-also>
</indexterm>
