quick fix to #36

Seems to fix #36, but I'm not really sure when the followin codepiece in bibsearch.js: getSearchResults() was *intended* to be used. AFAIK it could be removed altogether, but I don't really have the overview of the app yet...

```javascript
if (urlObj.hash.indexOf("?") == -1) {
      showSearchResults(undefined,undefined,undefined,urlObj,options);
      BookWorms.showSearchResults(undefined,undefined,undefined,urlObj,options);
       return;
     }
