Newly supported API Version 6 modifies `type=search` for _by_ type
`name-desc`: it now behaves the same as `name-desc` search through the
https://aur.archlinux.org/packages/ search page.

Search for packages containing the literal keyword `blah blah` AND `haha`:
https://aur.archlinux.org/rpc/?v=6&type=search&arg="blah blah"%20haha

Search for packages containing the literal keyword `abc 123`:
https://aur.archlinux.org/rpc/?v=6&type=search&arg="abc 123"

The following example searches for packages that contain `blah` AND `abc`:
https://aur.archlinux.org/rpc/?v=6&type=search&arg=blah%20abc

The legacy method still searches for packages that contain `blah abc`:
https://aur.archlinux.org/rpc/?v=5&type=search&arg=blah%20abc
https://aur.archlinux.org/rpc/?v=5&type=search&arg=blah%20abc

API Version 6 is currently only considered during a `search` of `name-desc`.
