You have access to eZ Find (and many other extensions) when downloading any of the eZ Publish Community Project builds, here : http://share.ez.no/download. Once unpacked the tarball, have a look in the 'extension' directory.
The eZ Publish Community Project Board is planning on also building these extensions independently of eZ Publish, every month. This shall make it easier to pick the usual extensions.
Finally, as Virgil mentioned, feel free to pick the extensions code directly off their repositories. All you need is on this page, listed on the left : https://github.com/ezsystems
Cheers !
