Yes, this is the modern approach. The only thing to be aware of in particular to Windows (and why I’ll leave this thread here instead of combining it with the existing thread on “NOT” searching in the Mac section) is that the implementation isn’t quite correct. It considers optional search scoping to be a part of what is not being looked for, when in fact those should modify, or filter, the overall results. For example, if you select the Draft Only option then inverting the results will not only discover items without a synopsis, but anything and everything not in the Draft, even if it has a synopsis. It should instead only show you items in the draft that do not have a synopsis.
So to get the best results use “Reset Search Options” first, and then only change the Search In setting to “Synopsis” and then of course the “Invert Results” setting. You’ll just have to ignore the chaff if you don’t want research items, trashed stuff, etc., which is usually not too difficult as the results are given in binder order.
