"WebGreedy: As Many As Possible (longest match) By default, a quantifier tells the engine to match as many instances of its quantified token or subpattern as possible. This behavior is called greedy. For instance, take the + quantifier. It allows the engine to match one or more of the token it quantifies: \d+ can therefore match one or more digits. " - Greedy vs backtracking
