When Hi HelpIndex starts, it reads the index file and displays the appropriate Contents, etc.
Hi Lab is your main tool to produce index files. (It also lets you edit Language files.)
So if you change your web site then you will need to update your index file. This is not done automatically.
A common use of more than one index file, is to have an English index, a French index, etc to match your English and French sets of web pages. You can specify up to two index files when using Hi Lab's wizard to build a new web page. Hi HelpIndex itself can cope with any number of index files.
