dpkg-query does not use a partial pathname as a pattern to search.

Example:
=> which exiftool
/bin/exiftool
=> dpkg-query --search `which exiftool`
dpkg-query: no path found matching pattern /bin/exiftool
=> dlocate `which exiftool`
libimage-exiftool-perl: /usr/bin/exiftool
=> dpkg-query --search /usr/bin/exiftool
libimage-exiftool-perl: /usr/bin/exiftool
=> /bin/ls -lt /usr/bin/exiftool /bin/exiftool
-rwxr-xr-x 1 root root 320936 Feb 2 19:43 /bin/exiftool
-rwxr-xr-x 1 root root 320936 Feb 2 19:43 /usr/bin/exiftool

This seems to be the intended behavior. In the dpkg-query(1) man page:

-S, --search filename-search-pattern...
[...]
If the first character in the filename-search-pattern is
none of ‘*[?/’ then it will be considered a substring match
and will be implicitly surrounded by ‘*’ (as in
*filename-search-pattern*).

Since your searches start with "/", you are requesting an exact match.

Using realpath solves the issue:

$ dpkg-query --search $(realpath /bin/exiftool)
libimage-exiftool-perl: /usr/bin/exiftool

You could write a small script that does what you want.
