+ If a show command goes to the boundary of a result set for a
+ database - depends on sorting - and pz:extendrecs is set to a positive
+ value. then Pazpar2 wait for show to fetch pz:extendrecs more
+ records. This setting is best used if a database does native
+ sorting, because the result set otherwise may be completely
+ re-sorted during extended fetch.
+ The default value of pz:extendrecs is 0 (no extended fetch).
