title: IdentifierSet Key Type role: manual tags: #manual #meta #reference #zettel #zettelstore syntax: zmk Values of this type denote a (sorted) set of [[zettel identifier|00001006050000]]. A set is different to a list, as no duplicate values are allowed. === Allowed values Must be at least one sequence of 14 digits (""0""--""9""), separated by space characters. === Query comparison A value matches an identifier set value, if the value matches any of the identifier set values. For example, ""000010060325"" is a prefix ""[[00001006032000]] [[00001006032500]]"". === Sorting Sorting is done by comparing the [[String|00001006033500]] values.
