Heh... some of the sites that bill themselves as teaching "advanced searching techniques" should be subject to a civil suit for false advertising. Of course, that's generally a redundant pair of terms...
All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.
From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.
