Site search label filter

How do I limit the results of the site search to a certain label?


VALUE is a label value.

Thanks for the quick answer. Is there a way I can set a label as default?

See Default Label Value.

Sorry, I meant somewhere in the settings of the site search form:

  (function() {
    var fess = document.createElement('script');
    fess.type = 'text/javascript';
    fess.async = true;
    fess.src = '//<Server Name>/js/ss/fess-ss.min.js';
    fess.charset = 'utf-8';
    fess.setAttribute('id', 'fess-ss');
    fess.setAttribute('fess-url', '//<Server Name>/json');
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(fess, s);
