Command pf (Package Finder) can search packages with a little easier syntax than yay or pacman.
For example, to search packages using words pdf and cups can be done as follows:
pf pdf cups # search both official and AUR software pf -o pdf cups # search only official packages pf -a pdf cups # search only AUR software
You can download and install it like this:
wget https://github.com/endeavouros-team/User-contributions/raw/master/manuel/pf chmod +x pf sudo cp pf /usr/local/bin
