ok, here I am in trouble. Being on *nix the '&' will be interpreted as
"putting process into background", so the wget command you give is not
working for me.

"man wget" tells me to use %3A:
{
You can encode unsafe characters in a URL as `%xy', `xy' being the
hexadecimal representation of the character's ASCII value.  Some common
unsafe characters include `%' (quoted as `%25'), `:' (quoted as `%3A'),
and `@' (quoted as `%40').  Refer to RFC1738 for a comprehensive list of
unsafe characters.
}
I tried that:

wget
"http://ckan.net/api/search/package?q=lobid&publishingInstitution=http%3A//lobid.org/organisation/DE-605"

but got an "400: Bad Request".

Is there a way to use curl , maybe with "curl --data" ?
