Can reproduce in trusty, but works properly in yakkety:

$ apt search -theme
E: The value 'heme' is invalid for APT::Default-Release as such a release is not available in the sources

Note that you cannot search package names starting with a -, as that is a special character for starting single character options (like -t).
