If <<.place S>> is empty, <<.op field>> will match both of the following:
* tiddlers that don't contain field <<.place F>>
* tiddlers in which field <<.place F>> exists but has an empty value
The syntax of a [[filter step|Filter Step]] treats any unrecognised [[filter operator|Filter Operators]] as if it was the suffix to the <<.op field>> operator.
