Query-based operators

A range of operators use a query as their scope, returning a List-type list of (unique) $Path values.

Such operators are:

• find(query)
• | (query logical OR join)
• < (less than)
• == (equality)
• > (greater than)
• <= (less than or equal to)
• >= (greater than or equal to)
• != (inequality)
• & (query logical AND join)
