Feature request

Hi guys!
I'm not sure whether this topic is already created. I didn't find it so I decided to create a new one.
Netbeans editor has a feature that shows a list of possible endings of the line when typing. E.g. when start typing 'req' a list with two suggestions ('require' and 'require_once') appears. This is a very useful feature, I always use it. 
But. Say I forgot the beginning of the command I want to type. I remember that there was something like 'once' in the end. I'm typing 'once', seeing nothing and going searching internet to find what I managed to forget. Other editors like Atom or Brackets would suggest me something so I don't waste time.
 Is it possible to add this feature in Netbeans as well?
