WordSet Key Type

Values of this type denote a (sorted) set of words.

A set is different to a list, as no duplicate values are allowed.

Allowed values

Must be a sequence of at least one word, separated by space characters.

Query comparison

All comparisons are done case-insensitive, i.e. “hell” will be the prefix of “World, Hello”.

Sorting

Sorting is done by comparing the String values.
