Smarter Engine needed

Nice Idea, but the search engine, or whatever it is needs to be a little bit smarter. It defined the city "NEW YORK" as 2 separate words. something new, and a city in Pennsylvania. Also isn't there a way to drop words like a, the, I? The Engine tried to define ever word. instead of vital words like advertised. This is Useless for my ESL/ EFL students. One needs to know the language before it can be used. Not use it to assist in learning what words mean for the 1st time
