<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.

Inheritance

+ topic/index-base indexing-d/index-see-also

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>

This will typically generate a page reference to "Carp" and a redirection:

  • 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
  • Goldfish
    • feeding, 56
    • flushing, 128, 345

The following example illustrates using a specialization of <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>
