+ F is a CCL field and N is the multipler for terms
+ that matches those part of the CCL field in search.
+ The F+N combo allows the system to use a different
+ multipler for a certain field. For example, a rank value of
+ "<literal>1 au 3</literal>" gives a multipler of 3 for
+ all terms part of the au(thor) terms and 1 for everything else.

For Pazpar2 1.6.13 and later, the rank may also defined
"per-document", by the normalization stylesheet.
