<p>Hi,</p>
<p>It's because space* accepts the zero-length string. So "abc" is actually three words with zero-length whitespace in between. Well, technically it's both that and what you want, so you need to remove the ambiguity. What you need is more like this:</p>
<p>space* wyraz ( space+ wyraz )*</p>
