This is the query I want to run:

/2.1/search?pagesize=100&page=1&order=desc&sort=creation&tagged=linux,ubuntu,bash,linux-mint,mint,linux-distributions,linux-distro,archlinux,&site=superuser&filter=.Ericv1w97*YhCWfY.uMVBr(o

Is it possible to search for more than 5 tags?

I would use /questions, but since it treats tags as AND instead of OR, I don't have any other option. Or do I ?
