This is not possible with Swish-e as far as I can tell. Swish-e only indexes 
what is present, not what is absent.

You could likely solve this by filtering your docs and passing to -S prog. Some 
simple regexp like:

  s,<(\w+)(.*?)>\s*</\1>,<$1$2>_no_tag_content_</$1>,gs;

would probably catch most of them. Then you could search for '_no_tag_content_' 
and find them that way.
