The level parameter specifies where the search starts. E.g. when you
index an object with the URL
http://www.zope.org//Wikis/DevSite/Proposals/PathIndexDocumentation
then the PathIndex uses its physical path for indexing. In this example:

'/Wikis/DevSite/Proposals/PathIndexDocumentation'

Searching for "DevSite" and level=1 would give you this document as search
result.
The first element of the physical path has level 0, the second level 1 and
so on.

Hope this helps,
Andreas
