I've translated forms and a few pages with CVS, and inline translation to get the scope. But these form options aren't selectable with inline book...
I've managed to translate "Catalog Advanced Search", "Search Settings" and "Search" in CVS, but I have no idea how to translate attributes.
Here's catalogsearch/advanced/form.phtml
