I just did a search on a disk using Folders Only, but was surprised when the expected folders didn't show up.
Then I noticed that there was some text in the "Containing Text" field from a previous "Files Only" search. When I cleared that, the folders showed up in the next search.
Shouldn't that be ignored when you do a "Folders Only" search, since folders don't contain any text?
Another thing: how about a checkbox option that determines whether the "Containing Text" field should be automatically cleared or not, after a search? Sometimes you forget to clear the field and then you may not find the files you search for because they don't contain the text in the field. If you however want to do several searches using the same text criteria, you just check the box.
