Simple search engine (POST or URI?)

I personally prefer the second method, for the same reasons you mentioned: bookmarking, c/p...

In my app, I created a method that handled the actual search action (the post), i processed the query with url_title and then redirected to a new uri with that string attached to it. This provides a nice clean url and you have everything you need: the search words.

You can then decide if you want to search word by word (explode the string with the - ) or use the entire string to perform your search (replacing - with " ").

Mind you, there's probably some downsides to my method, but it's all I needed.
