Since we've just implemented a new search back-end, this info can be considered deprecated - HB
The forum search engine deems some terms such as "compound", "node" or "render" too "common" to be searched for
Inspired by a tip that Stephen recently posted here
, you can cheat around this by using wildcard searches such as:rende* nod* compoun*
Note that wildcards have to be at the beginning or end of each search term.
Also, as an alternative, Hirazi Blue has created a Custom Google Search Engine:http://tinyurl.com/si-community
