I've added support for basic searching. Currently it only searches the body of each article. I plan on expanding that at some stage. I might write up what it supports (syntax) later.
Yeah well it seems to work without a submit button and it validates so it must be okay, plus I don't really want a button there. I might move the search thing anyway. Just playing with it.
The code is a slightly modified version of this. I'm going to need to check the license on that one. I don't think I'd be able to write a replacement for that. Although I'm sure there are free search classes.
Ironic, that this article doesn't show up if you search for "search", as "search" isn't in the body, but "searching" is -- hence its absence from the results. I can see why spaces on both sides of a word would be useful in searching, so if I searched for "arched" I wouldn't get results for "searched", but it's still... yeaaah... I don't know anything about how it works, though, so it looks cool :P
I'm noticing an absence of a "Submit" button and form action, though... should that work?
