Let's clarify one thing: the online Spanish dictionary (and the various dictionaries under this umbrella) published and maintained by the Real Academia Española are not limited to European Spanish usage. For instance, search the word “computadora” and you'll find a rich and detailed entry, along with synonyms and associated words like “computador” and “ordenador”.
In short, the RAE dictionaries we see online encompass the Spanish language in all the countries it is spoken; that applies to the ones published by the Spanish Engineering Academy and the Diccionario Panhispánico de Términos Médicos, among others.
So, Alisha, I've done some of the research for you. Use it.
