Returns a Catalog object containing up to
20 full English card names that could be autocompletions of the given string parameter.
This method is designed for creating assistive UI elements
that allow users to free-type card names.
The names are sorted with the nearest match first, highly favoring
results that begin with your given string.
Spaces, punctuation, and capitalization are ignored.
q is less than 2 characters long, or if no names match,
the Catalog will contain 0 items (instead of returning any errors).
