pacman -Qs string1 string2 returns nothing

I can do this:

$ pacman -Qs libdmx
local/libdmx 1.1.4-1

and this:

$ pacman -Qs libxxf86dga
local/libxxf86dga 1.1.5-1

but this returns nothing:

$ pacman -Qs libdmx libxxf86dga

which isn't normal, or as recommended in pacman > Querying package databases.
Any ideas why?

Re: pacman -Qs string1 string2 returns nothing

It's a regex string search, both strings must be part of the description, if you want a package information print out drop the -s

man pacman wrote:

-s, --search <regexp>
           Search each locally-installed package for names or descriptions that match regexp. When including multiple search terms, only packages with
           descriptions matching ALL of those terms are returned.

Re: pacman -Qs string1 string2 returns nothing

But, man pacman says

       -s, --search <regexp>
           Search each locally-installed package for names or descriptions that match regexp. When including
           multiple search terms, only packages with descriptions matching ALL of those terms are returned.

Re: pacman -Qs string1 string2 returns nothing

The above are, or course, correct.  But it's a bit odd to use the -s flag at all in your case.  If you know the package names, you don't need to search.  This will work:

pacman -Q libdmx libxxf86dga
