Cannot match some words

[Bongsakorn]

First, Thank you for your gem. it's very awesome.but there are something wrong, perhap.

I inserted words "central" and "#central".

matcher.insert("central", "#central")

then I tried to match the sentence "I would like to go to #central".

matcher.match("I would like to go to #central")

I just got ["#central"] returned. Actually, It should be ["central", "#central"]. shouldn't it?
