Note that if a tiddler does not contain field <<.place F>>, it is treated as if the value of the field were empty. Thus, a filter expression such as `[each[color]]` will return one tiddler that doesn't have a `color` field. To obtain just the tiddlers that have a non-blank value for the `color` field one can use `[each[color]has[color]]`.
Note that if a tiddler does not contain field <<.place F>>, it is treated as if the value of the field were empty. Thus, a filter expression such as `[each[motovun]]` will return one tiddler that doesn't have a `motovun` field, as well as one tiddler with each distinct value of that field, if any. To obtain just the tiddlers that have a non-blank value for the `motovun` field one can use `[each[motovun]has[motovun]]`.
