dupe: in Everything 1.4 is rather limited.
dupe: in Everything 1.4 will find duplicated items in your
entire index, not the current results.
It works best when used on its own, without other search parameters.
For example, use sizedupe: and sort by size descending.
Everything 1.5 will have support for finding duplicates in your results.
dupe:name will only work in
Everything 1.5.
