    * Examples:\n
        sisyphus search openbox\n
        sisyphus search x11-wm/openbox\n
    \n
    Using * and ? wildcards is supported. An empty string will match everything (similar to *).\n

        sisyphus search x11-wm/     # search all packages in the x11-wm category\n
        sisyphus search x11-wm/*    # search all packages in the x11-wm category\n

    * Examples:\n
        sisyphus search x11/open -d 'window manager'    # use single or double quotes when the description contains spaces\n

    \n
        all (default)   - search the entire database\n
        alien           - search for installed packages but not available     # (this filter can match packages installed from ebuilds or packages no longer maintained as binaries)\n

    \n
    !!! NOTE !!!\n
    \n
    Bash will expand a single * character as current folder listing.\n
    To search for all matching '--filter' packages you need to escape it, surround it with quotes, or just use an empty string.\n
