POST parameters don't work

Hi,

I tried to set up a shortcut that uses POST parameters---and failed. While, e.g., a simple

wget --post-data 'anywords=Incoercible Multiparty Computation' https://eprint.iacr.org/eprint-bin/search.pl -O search.pl.html

works from the command line, it does not seem to work for the shortcut (POST parameters set to: anywords={%query} ).

The actual form website is at https://eprint.iacr.org/search.html .

Any idea what's wrong?
