Hi.
I’m very new to fess.it’s fantastic app.

What type of link (anchor or button) will click by fess to web crawl?
I’m tring to crawl my a few redmine site.
Should I exclude any url pattern to avoid delete or updating my tickets or dmsf file and redmine settings.

Fess follows links in transformer_basic.xml.

thank you so much.
and every url will request by get method?

and my note…
issue journal delete -> using put method -> ok(must be)
issue delete using delete method -> ok(must be)
issue update using submit form -> ok
dmsf file delete -> using get method -> ng
and may more…

should be including determinate urls to crowling and indexing. like /issues/.*

(from github.com/marevol)
It’s GET request.
