Hum! The examples should be inside the man page, not outside.

which lacks examples. Once I know that I have to specify the package type,
yes, I can see it in the help.
That's what is supposed to explain with the 'default' in every zypper
command (install, upgrade, update, etc):
-t, --type <type>               Type of package (%s).\n
                               Default: %s.\n

]

] location. A capability is NAME[OP<VERSION>], where OP is one of <, <=, 
] =, >=, >.

It is above where it should tell that the package type has to be 
specified, and which is the default, not below - IMO:

]  Command options:
] -r, --repo <alias|#|URI>       Install packages only from the specified 
]                                repository.
] -t, --type <type>              Type of package (package, patch, 
]                                pattern, product).
]                                Default: package.

The phrasing is not very fortunate.

Seams that the man page of zypper was remade some weeks ago, I don't
remember in which list it was announced...
The current man page, where you look at the command install, does not 
mention "patterns":

]      install  (in) [options] <name|capability|rpm_file_uri> ...
]             Install or update packages.
]
]             The  packages can be selected by their name or by a
]             capability they provide.
]
]             Capability is: NAME, or "NAME[.ARCH][OP<EDITION>]",
]             where  ARCH  is  architecture code, OP is <, <=, =,
]             >=, or >  and  EDITION  is  VERSION[RELEASE].   For
]             example: zypper=0.8.82.
]
]             The  NAME  component  of a capability is not only a
]             package name but any symbol provided  by  packages:
]             /bin/vi, libcurl.so.3, perl(Time::ParseDate).  Just
]             remember to quote to protect the special characters
]             from the shell, for example: zypper\>0.8.10 or zypϖ
]             per>0.8.10
]
]             If EDITION is not specified, the newest installable
]             version will be installed.  This also means that if
]             the package is already installed and newer versions
]             are  available,  it will get upgraded to the newest
]             installable version.
]
]             If ARCH is not specified, or the last  dot  of  the
]             capability  name  string  is  not followed by known
]             architecture,  the  solver  will  treat  the  whole
]             string  as a capability name. If the ARCH is known,
]             the solver will  select  a  package  matching  that
]             architecture and complain if such package cannot be
]             found.
]
]              Zypper will report packages that  it  cannot  find.
]             Further,  in interactive mode, zypper proceeds with
]             installation of the rest of requested packages, and
]             it  will  abort immediately in noninteractive mode.
]             In    both    cases     zypper     returns     ZYPϖ
]             PER_EXIT_INF_CAP_NOT_FOUND   after   finishing  the
]             operation.
]
]             Zypper is also able  to  install  plain  RPM  files
]             while  trying  to  satisfy their dependencies using
]             packages from defined repositories. You can install
]             a  plain RPM file by specifying its location in the
]             install command arguments either as a local path or
]             an URI. E.g.:
]
]             $        zypper        install       ~/rpms/foo.rpm
]             http://some.site/bar.rpm
]
]             Zypper will  download  the  files  into  its  cache
]             directory (/var/cache/zypper/RPMS), add this direcϖ
]             tory as a temporary plaindir  repository  and  mark
]             the respective packages for installation.
]
]             In  the install command, you can specify also packϖ
]             ages you wish to remove in addition to the packages
]             you wish to install, by prepending their names by a
]             or ~ character. For example:
]
]             $ zypper install vim emacs
]             $ zypper remove emacs +vim
]
]             will both install vim and remove emacs.  Note  that
]             if  you  choose  to use  with the first package you
]             specify, you need to write  before  it  to  prevent
]             its interpretation as a command option.
]
]             $  zypper  install  boringgame greatgame greatgameϖ
]             manual

If you position the cursor in the man page at the "install" command, and 
you search for the word "pattern", you will see it first appears on the 
"remove" command, not on the "install" command.

I looked for the info on how to install patterns looking on the man page 
for the "install" command, and then for how to install a pattern searching 
for the word "pattern" - and after I couldn't find it, I had to ask here.

If, on the man page you look for the modifiers of "install", you see:

]      t, type <type>
]              Type of package (default: package). See the  beginϖ
]              ning  of  this subsection for the list of available
]              package types.

Again, "pattern" is not mentioned.

Thus, IMO, the man page is not good enough for a person that doesn't 
already know how to use zypper.
