How may I identify the line return/carriage return in Writer?

I need to do something I used to do with Word 2007 and 2010 but I don’t know how to do the same in Writer.
Let’s imagine I have a document with these names.

  1. JOHN
  2. PAUL
  3. MIKE

Okay. Every name jump to the next line, so they have a line return or carriage return if you prefer.
That, in Word is controlled with the character ^p
So if you tell Word find me the ^p character and (for example) replace it with an hyphen -
what Word would do is this

  1. JOHN-2. PAUL-3. MIKE
    Because it will search for the line return and replace it with an hyphen -
    But how may I do this in Writer?
    I have seen the search dialog box which is full of options and possible settings to search for, as color, font types, etc. but I did not find how to search the line return ?

You could search for: \n (line break) or $ (paragraph),
see also → Find & Replace doesn’t find paragraph marks.
