<lst name="facet_fields">
    <lst name="regionId">
        <int name="1">4</int>
        <int name="10">11</int>
        <int name="11">14</int>
        <int name="12">6</int>
        <int name="13">38</int>
        <int name="2">1</int>
        <int name="3">4</int>
        <int name="4">1</int>
        <int name="5">5</int>
        <int name="6">8</int>
        <int name="7">0</int>
        <int name="8">27</int>
        <int name="9">5</int>
    </lst>
