+       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.
