Hi

This is a rather simple question. I assume that you are new to 
LilyPond, so let me explain how to search the answer in the 
documentation.

I suggest starting from the index of the Notation Reference:
http://lilypond.org/doc/v2.18/Documentation/notation/lilypond-index

If you click on the B and search for breaking, you quickly find:
http://lilypond.org/doc/v2.18/Documentation/notation/line-breaking

and at the bottom of that page:
http://lilypond.org/doc/v2.18/Documentation/notation/other-paper-variables#paper-variables-for-line-breaking

So you have two tools:

1. \break for "hard" breaks (I suggest using it rarely, only where you 
really want to force a line break)
2. \paper variables: this is what you'd like to use mostly, as you can 
usually change the line breaking of a whole score with one or two 
options without touching the music (easier to maintain and change later)
