Collection-Level .HxK File
A collection-level .HxK file indicates the existence of a particular index in the Help collection. That is, although the .HxS and .HxI files that make up your collection can define indexes, those indexes will not be exposed to the user unless you include a corresponding .HxK collection-level file. For example, if an .HxS file in your collection defines a K-keyword index and an A-keyword index that you want to expose, you would need to add two collection-level .HxK files—one for each index.
Index Example
The following example shows a collection-level .HxK file for a K-keyword index:
<?xml version="1.0"?>
<!DOCTYPE HelpIndex>
<HelpIndex
DTDVersion="1.0"
Name="K"
Id="HelpCol_K"
AutoInclude="Yes"
Merge="Yes"
Sort="Yes"
Title="Keyword Index"
Visible="Yes"
LangId="1033"
>
</HelpIndex>
Note
Keywords defined in collection-level .HxK files are ignored.
