-e, --explicit

Filter to explicitly installed packages only

-d, --deps

Filter to packages installed as dependencies

-t, --unrequired

Filter to packages not required by any other package

-o, --owns file

Search for the package that owns the specified file

-i, --info

Display detailed package information

-l, --list

List files owned by the package

Filter to packages not found in sync databases (AUR packages)

Filter to packages found in sync databases

-u, --upgrades

Filter to out-of-date packages

-q, --quiet

CAVEATS

The query operates on the local database only. Use pacman -S for sync database operations. Orphan packages (installed as dependencies but no longer required) can be found with -Qdt.
