+Implemented sorting via the ISAMB system. To enable, use sortindex:b
+in zebra.cfg. The sort keys can also be fetched using zebra::sort:field .
+
+Added support for specification of approximative limits for whole query.
+This is specified as attribute type 12. Semantics is the same as
+estimatehits in zebra.cfg.
