- How do i understand what a correlation function is and what i can do with it

Hello, recently I'm learning about correlation functions in the context of QFT. Correct me with I'm wrong but what i understand is that tha n-point correlation functions kinda of describe particles that are transitioning from a point in space-time to another by excitations on the field. So, what i need help is that i have a field and this field is solution to the classic equations of motion (i.e. it was obteined via hamilton-lagrange equations of motion). I want to know, if it's possible, how to use this field in a correlation function, if it would have any physical meaning and if i can obtain anything from it. Meaning, how do i use a specific field solution and get some sort of result (in this case a probability i guess). I hope I've been clear because english is not my native language so maybe something is not right or confusing.
