Google based[edit]
This one should work better than the regular site search which seems unreliable sometimes.

Sorry, i cannot default this to s23 due to Google rules.
IRC based[edit]
But you can also search on IRC, #wiki on EfNet by using
.content <keyword>
.title <keyword>
But even that search seems to need fixing, so now we got 3 different ways to search but none is perfect ;)
