Well, no one really knows the mysterious workings of the Google spiders. Except the people who made them and they all signed non-disclosure agreements. Google says they handle dynamic urls fine now, but this hasn't always been the case, and there's a lot of speculation that they still can't go more than two parameters deep in a dynamic url. So using this url again as an example, they'd maybe get as far as the topic id but not the start parameter, so they wouldn't index multiple pages of a topic. And other modules might have even more parameters than this in the urls.
I have done this:
1. mod_rewrite is loaded
2. Changed .htaccess: RewriteBase /
3. Changed .htaccess: RewriteRule ^index\.html /index.php
4. In httpd.conf i have in <Directory /> Options FollowSymLinks
5. Emptied the cache directory
6. I also checked for more info in www.cpgnuke.com/Forums...art=0.html
Server specs (Server OS / Apache / MySQL / PHP / DragonflyCMS):
I assumed that was not the real spec of the live webserver you planned to use. There are supposedly ways to get .htaccess to work on Apache on Windows, but I'm at the end of my advice on it if that's really the case.
