IF you visit:
http://www.google.com/custom?domains=ir ... eforge.net
or click 'Search' on the main Irrlicht website, the search results you query thru mysql/php are not being retrived properly.
Here's a good example I hope. Visit the search site [above] and look for 'playernode'. It should fetch only one respone from the google database. When you click it you will see this is not the intended thread at all. To confirm, search the newly opened thread with your internet browser for 'playernode' and it will say "finished searching document". It is defintly not the same result for me anyways.
I don't know what layer this exists at [the google dB or the Irrlicht dB] but I think it should be investigated into. Hope this helps, GL!
