Comment (by karsten):

 Hmm, I see the use case where somebody would only want to learn about
 verified host names. However, I'm not sure whether the suggested approach
 of splitting the `host_name` parameter into two parameters is the best way
 to do this.

 An alternative would be to make it clearer in the documentation that
 results include relays with verified and unverified host names ending in
 the given search string. And whoever makes this query and cares about the
 verified/unverified bit would then have to filter the results locally.

 Which option is less surprising? Seeing an interface with two very similar
 parameters, which by the way cannot be used together in a single query,
 plus the possible confusion when a request with one such `*_host_name`
 parameter will not return all relays with that host name? Or a situation
 in which a result contains both verified and unverified host names?

 To be clear, the effort for adding two new parameters on existing data is
 relatively small. My main concerns are that we'd slowly clutter the
 interface and that this does not seem like a clear improvement over what's
 there.

 Regarding your last suggestion of accepting multiple values, let's discuss
 that regardless of whether we're splitting the parameter or not. If it
 makes sense to search for (verified or unverified) host names ending in
 different strings, let's consider doing that.
