For anything fuzzier, you'll be better off with Google. There's a reason Google is a trazillion dollar company and we are just 3 guys in a windowless, musty basement with a single unshaded lightbulb hanging down from a frayed electrical extension cord.

EDIT: We now force any terms in your search which map directly to a top 40 tag, to be that tag. In other words, if you search for

the system will auto-convert this to
[c++] pointers
on your behalf
