     Sorting applies to a result-set.

+  <para>
+   Like Type-1/RPN, YAZ supports a string notation for specifying
+   facets. For the API this is performed by
+   <function>yaz_pqf_parse_facet_list</function>.
+  </para>
+  <para>
+   For ZOOM C the facets are given by option "facets"
+   For yaz-client it is used for the facets command.
+  </para>
+  <para>
+   The grammar of this specification is as follows:
+   <literallayout>
+   facet-spec ::= facet-list
+
+   facet-list ::= facet-list ',' attr-spec | attr-spec
+
+   attr-spec ::= attr-spec '@attr' string | '@attr' string
+
+   </literallayout>
+    The notation is inspired by PQF. The string following '@attr'
+    may not include blanks and is of the form
+    <replaceable>type</replaceable><literal>=</literal><replaceable>value</replaceable>,
+    where <replaceable>type</replaceable> is an integer and
+    <replaceable>value</replaceable> is a string or an integer.
