This is simpler than you're trying to make it.
Try this experiment
gpg --keyserver pool.sks-keyservers.net --search-keys gswot
Note that the search results returns the key and all the UIDs if just one of the
UIDs contains your search term. The keyservers break a UID down into words and
index each word. If I search for MFPA, I'll get all keys that have an UID
containing MFPA along with all the UIDs on those keys.
To achieve the two goals, you only need to put each in its own UID. Just
remember once they locate the matching key, they will have all the information
in all the UIDs. You may need --allow-freeform-uid as Werner pointed out earlier
when creating these User IDs.
Sorry, but there is no way to only return a single UID matching the search term.
Things were never designed that way. (So there's really no reason not to put all
three in a single ID.)
