  <view type="text"/>
</query>

To open the list of people who Mike knows:

<query>
  <text>Mike</text>
  <view type="properties"/>
</query>

To show the list of subjects Mike knows:

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <view type="list" />
  </property>
</query>

To show the properties of people Mike knows:

<query>

To show the names:

<query>

To specify one named Joe:

<query>

  <property iri="foaf:knows>
     <property iri="foaf:name>
        <value>Joe</value>
     </property>
    <view type="properties" />
  </property>
</query>

This lists the properties of the friends of Mike that are called Joe.

To show the Mikes that know a Joe, one would change the shown variable in the navigation and get:

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
   </property>
   <view type="text" />
</query>

This would be the search summaries of subjects with Mike in some field that know a subject with name Joe.

Now to specify that Mike must be a member of a discussion board:

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
     <value>Joe</value>
   </property>
  </property>
  <view type="property-in" />
</query>

This lists the properties of triples whom object is Mike. Pick sioc:member_of

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
  </property>
  <property-of iri="sioc:member_of>
    <view type="list" />
  </property-of>
</query>

This would show things where Mike is a member. To specify that the thing must be a forum:

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
  </property>
  <property-of iri="sioc:member_of>
    <view type="classes" />
  </property-of>
</query>

This shows classes of things where Mike is a member Clicking on sioc:Forum gives:

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
  </property>
  <property-of iri="sioc:member_of>
    <class iri="sioc:Forum" />
    <view type="classes"/>
  </property-of>
</query>

The view stays with classes, but now scoped to the classes of things where Mike is a member that are instances of sioc:Forum.

To go look at the list of Mikes with the added restriction, click the shown variable in the navigation and set it to s1.

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
  </property>
  <property-of iri="sioc:member_of>
   <class iri="sioc:Forum" />
  </property-of>
  <view type="list"/>
</query>

To say that Joe must also have a geekCode, One clicks the shown variable and sets it to s2 and the view to properties.

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
    <view type="properties"/>
  </property>
  <property-of iri="sioc:member_of>
    <class iri="sioc:Forum" />
   </property-of>
</query>

<query>
  <text>Mike</text>
  <property iri="foaf:knows>
    <property iri="foaf:name>
      <value>Joe</value>
    </property>
    <property iri="geekCode">
      <view type="list"/>
    </property>
  </property>
  <property-of iri="sioc:member_of>
    <class iri="sioc:Forum" />
  </property-of>
</query>
