Quantifiers

Odinson supports a full range of quantifiers which can be applied to any pattern element (i.e., tokens, graph traversals, or combinations of these).

Quantifier	Description	Example
?	indicates a pattern element is optional	>amod?
*	matches zero or more of an element	[]*
+	matches one or more of an element	(>amod [])+
{m, n}	matches at least m and at most n of an element	>>{2,3}

Odinson also supports both greedy and lazy usage of these quantifiers. For example, [tag=/N.*/]+? will perform lazy (or reluctant) matching of nouns.
