Fess Web crawler appears to ignore relative links in some cases.

(from github.com/burple6)
Given the following HTML code, FESS fails to see the linked pages:
<a href="start-here.html">Start Here</a> <a href="our-brand.html">Our Brand</a> <a href="logo-basics.html">Logo Basics</a>

If the links are changed to absolute links, FESS crawler sees and crawls them.

This issue is happening when crawling the site http://med.umich.edu/branding/index.html. Included URL patterns are ".*/med.umich.edu/branding/.*".

It was not produced. It works.

You are correct, this was resolved by clearing the crawler indices and crawling again.
