 - A `discovery-method` may contain multiple `match-property` entries, and in such a case **all** entries must match i.e. it a logical `AND` function is applied.
 - If you want to apply a logical `OR` function you can define a second separate `discovery-method` containing the respective `match-property` entry.
+- Different add-on discovery finders may need different `discovery-parameters`. Check the JavaDoc of the respective finder. See the `mdns` example below.
