Adding to what I said below I suppose 'buscar' a secas is 'look for' when something is lost. 'Buscar en el diccionario' is 'consultar' 'Buscar un coche o una persona' is 'recoger' but in Spanish 'buscar' can also be used for all of them.

Hi, "Buscar en el diccionario" to look through "Buscar un trabajo" to look for a job, "Buscar mi coche" to look for my car "Buscar a un amigo"... to take my friend by car ..or ... to pick my friend up Have a nice day

yes..you're right. You look a word up in the dictionary or look up a word. You look for a new job in the newspaper for example. You look for your car if it's lost or maybe collect it or pick it up if it's at the garage being repaired. You meet a friend if you've already decided to meet or call for a friend if you go to his/her house and you are a young person probably a child."let's go and call for Maria" Another one is to pick your son/daughter up at school at the end of the day. So it really depends what you are 'buscando' and whether it's lost or not.

But....in English, of course....thanks!!!! =D
