The maintainer may associate an arbitrary field value to any document in the WN hierarchy. It is then possible to do fielded searches.
A line like:
Field3=any text here
in the index file
associates the text "any text here" with user
defined Field3. The '3' in this example can be
replaced with any number from 0 to 19. A fielded search is invoked by a
URL like:
http://host/dir/search=field3
In addition to fielded searches the user supplied fields can be inserted in documents. This is done by including a field marker such as:
<!-- #field3 -->
in the file at the point where the value should be inserted. If there is
no Wrappers= or
Includes= line in
the index file for this
entry then there must be a line like:
Attributes=parse
so the server knows it is to parse the file to look for the marker. See the section "Set File Attributes" in this guide for more details.
