I'm guessing there is a translation error here because I don't understand what you're trying to say.
pamac is not a magic push button compiler / packaging tool. It just has the ability to install things via the AUR (Arch User Repository) which itself is just a heap of community made packages which Arch does not officially support in their main repository. There is no magic, somebody still went to the effort of figuring out how to compile and package it, example https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=budgie-desktop-git
Solus does not have their own version of the AUR (SUR) and has no intention of ever having one, in addition anything built specifically for Arch is not going to work on Solus.
As for "automatic research" I can only assume you mean to say that Solus software center has no
"automatic search when you type something"
In which case if the developers choose to implement that feature they would do so with the planned software center rewrite.
