Placing an Entry Under Two Headings

Help > Authoring > Table of Contents and Index > Sorting Index Terms > Placing an Entry Under Two Headings

To have an entry appear under two headings in the index, include two index elements for the same entry. Add a sortas attribute value for one of them. The following example generates an index entry for Psychiatry under both P and S.

<indexterm><primary>Psychiatry</primary></indexterm>

<indexterm><primary sortas ="S">Psychiatry</primary></indexterm>

This example is in “raw” XML. When you add the sortas attribute in the Modify Attributes dialog box, you do not include the quotation marks. You simply add S for the value.

Remember that the sort key is case sensitive. The following example is incorrect:

<indexterm><primary sortas="f">Phlox</primary></indexterm>

<indexterm><primary sortas ="F">Philodendron</primary></indexterm>

Phlox would sort before Philodendron under the F alphabetical heading in the index.

Give indexterm elements the same sort key if they are related, and you want them all to appear under the same alternate heading.

<indexterm><primary sortas="K">Cookies</primary>
<secondary>Chocolate Chip</secondary></indexterm>

<indexterm><primary sortas ="K">Cookies</primary>
<secondary>Oatmeal Raisin</secondary></indexterm>
