Remote Desktop Manager use the C# nomenclature (&& for AND, || for OR).
Evaluated left-to-right.
No parentheses matching.
Double-quotes (") are not required or removed, they are part of the text filter, do not use them unless you are looking for a double-quote.
Leading/trailing white-spaces are trimmed.
