Previously, searching for hosts by an explicit label under Setup > Hosts (via the Search for hosts display action) only compared the label key and ignored the label value. For example, searching for the label "dc:MM" also returned hosts with "dc:MG", since both share the key "dc".

This has been fixed. The host search now matches the full label, so only hosts carrying the exact "key:value" pair are returned.
