+      YAZ Frontend Virtual

+   <para>
+    For example, using server-side CQL-to-PQF conversion, one might
+    query a zebra server like this:
+    <screen>
+    <![CDATA[
+     yaz-client localhost:9999
+     Z> querytype cql
+     Z> find text=(plant and soil)
+     ]]>
+    </screen>
+     and - if properly configured - even static relevance ranking can
+     be performed using CQL query syntax:
+    <screen>
+    <![CDATA[
+     Z> find text = /relevant (plant and soil)
+     ]]>
+     </screen>
+   </para>
+
+   <para>
+    By the way, the same configuration can be used to 
+    search using client-side CQL-to-PQF conversion:
+    (the only difference is <literal>querytype cql2rpn</literal> 
+    instead of 
+    <literal>querytype cql</literal>, and the call specifying a local
+    conversion file)
+    <screen>
+    <![CDATA[
+     yaz-client -q local/cql2pqf.txt localhost:9999
+     Z> querytype cql2rpn
+     Z> find text=(plant and soil)
