The file docindex.html was
produced by the WN utility wnindexmaker.
wnindexmaker produces a collection of HTML unordered lists
with entries like:
<li> <a href="search=context?content-type">content-type</a>
This is an anchor to a relative URL. The complete URL would be:
http://host/docs/search=context?content-type
which asks the server to do a context
search of the 25 files in the User's Guide
with query term "content-type". When this is selected the
server returns a list of all files in the directory with matches, with a
sublist for each list consisting of the lines that contain a match.
Selecting one of the highlighted search terms in a match line causes the
server to return document positioned at the location of the matched
item. This is part of all context searches. It is done by inserting an
anchor on the fly at the location of the match.
