How to use <> not operator with search columns ?

[anmac1789]

How do I use the <> which means not for a search parameter ? for example find all files/folders where media-created:<> which is supposed to mean empty/has no data etc..

[void]

To find files/folders where media-created: is not empty, include the following in your search:

media-created:



Alternatively, Everything has an unknown keyword.
unknown will match the empty value.

media-created:!=unknown

Use != for NOT EQUAL.

do you mean to use it as

$media-created:==$unknown

With $media-created:, use:

$media-created:!=
-or-
$media-created:<>

$media-created: is slower than media-created: as the expression is evaluated.
