#### 16.5.8 Customizing index sort order

For stand-alone (unmerged) HTML Help and for OmniHelp, as well as for non-Help HTML (see §14.8.6 Configuring index features for HTML output), DITA2Go can control the order of index entries and subentries. Merged HTML Help requires a binary index, which ignores DITA2Go settings. JavaHelp and Oracle Help tend to ignore any sort order DITA2Go produces.
