After selection of multiple Refiners:
Add the following javascript to the Search results page:
<script type="text/javascript">
function Filter(url)
{
var inputs = document.getElementsByTagName("input");
var idValues = [];
for (var i = 0; i < inputs.length; i++) {
if ((inputs[i].type == "checkbox") && (inputs[i].checked)) {
idValues.push((GetUrlKeyValue("r",false,inputs[i].value)).substr((GetUrlKeyValue("r",false,url)).length));
}}
window.location = SP.Utilities.UrlBuilder.replaceOrAddQueryString(url, "r", GetUrlKeyValue("r",false,url)+decodeURI(idValues.toString().replace(/\,/g,"%20")));
}
</script>
(2012-03-01) Correction: changed the boolean value in all three GetUrlKeyValue functions to false.Extend the XSL of the Filterlink template in the Refinement Panel web part:

That's all folks!
Notice: The Display Language should be English, because I check for the word 'Any' in the XSL. You can/should adjust this by yourself in rows 30, 33, 36 for your preferred language.
Zip file with two webparts:
- HTML Form Web Part.dwp with navigation and the javascript;
- Refinement Panel.webpart with the extended XSL and customized categories.
Add the web parts to the Left Zone in the Search results page, and remove the original Refinement Panel web part.
