A query directive transforms a list of zettel identifiers into a list of zettel identifiers.
It is only valid if a list of zettel identifiers is specified at the beginning of the query expression.
Otherwise the text of the directive is interpreted as a search expression.
For example, ''CONTEXT'' is interpreted as a full-text search for the word ""context"".

Every query directive therefore consumes a list of zettel, and it produces a list of zettel according to the specific directive.
