I've searched extensively, but was unable to find much useful information. Can somebody please shed some lights on this?

(info "(org) Using the mapping API") was the first doc I read which has very little information on how to use the "match" parameter. (info "(org) Matching tags and properties") does have a lot more detail though.

However, this will also exclude the trees whose property value is empty, for example, the following tree will be excluded, which will not be excluded if "myproperty<>nil" syntax works: * Tree :PROPERTIES: :myproperty: :END: But there's probably no point to have such empty property after all. So you approach is acceptable. Thanks!
