I have just ported my own Search snippet to Revolution.
As I have only just done this, I can only claim it to be at an alpha stage. Bug reports are welcomed and regarded as inevitable at this point. The Evo version is refered to here

Its not like AjaxSearch. You could use it to generate an Ajax server response if thats what you want, but you’d have to be able to write the javascript yourself.
I haven’t used SimpleSearch but I don’t think that can search TVs as yet, whereas this code will.
Note that the search form is static HTML and inserted as a chunk. The search results are generated by the snippet.
