Each manual has an index, based on the contents of the manual.
Here's an example from the Acquisitions manual: http://docs.evergreen-ils.org/reorg/3.1/acquisitions/_index.html
The docs can be searched by keyword, so we don't need to index every concept. Our index is most useful for words or spellings that don't exist within the text. This might be synonyms, aliases, abbreviations, acronyms, etc. Some examples:
Each entry in the index gets its own ASCIIDoc indexterm
command, starting from the most general entry, and going to the most specific. Here's an example:
indexterm:[self check interface,audio alerts] indexterm:[self check interface,checking out]
This will produce two entries in the index:
self check interface audio alerts checking out
Run the following command in the main Evergreen directory.
grep -rL indexterm docs | grep /.*adoc | grep -Ev 'TechRef|RELEASE|root'
