API Version 6 modifies `type=search` functionality: Split `arg` into keywords separated by spaces (quoted keywords are preserved).
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 only considered during a `search` of `name` or `name-desc`. Note: This change was written as a solution to https://bugs.archlinux.org/task/49133. PS: + Some spacing issues fixed in comments.
