       To perform a global search to match the pattern as many times as it
       appears in the source string, provide a true value for the "global"
       argument following the pattern.

           [% text = 'bandanna';
              text.match('an+', 1).join(', )      # an, ann
           %]

So, to get the count:

[% text.match('no', 1).size %]
