Solr: Высокий приоритет в полях

Я пытаюсь выполнить поиск в solr, но хочу отдать приоритет поиску поля (например, заголовка) над совпадением в других полях, таких как «Директора». Это часть моего schema.xml

<fields>
    <field name="Id" type="string" indexed="true" stored="true" required="true"/>
    <field name="Title" type="text_general" indexed="true" stored="true"/>
    <field name="OriginalTitle" type="text_general" indexed="true" stored="true"/>
    <field name="Directors" type="text_general" indexed="true" stored="true" multiValued="true" required="false"/>
    <field name="Language" type="text_general" indexed="false" stored="true" required="false"/>
    <field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/>
</fields>

<uniqueKey>Id</uniqueKey>

<defaultSearchField>text</defaultSearchField> 

<solrQueryParser defaultOperator="OR"/> 

<copyField source="Title" dest="text"/>
<copyField source="OriginalTitle" dest="text"/>
<copyField source="Directors" dest="text"/>
<copyField source="Keywords" dest="text"/>

Это мой обработчик запросов:

<lst name="responseHeader">
  <int name="status">0</int>
  <int name="QTime">2</int>
  <lst name="params">
    <str name="lowercaseOperators">true</str>
    <str name="pf">Title^100 Directors^10</str>
    <str name="indent">true</str>
    <str name="q">fo*</str>
    <str name="qf">Title Directors</str>
    <str name="stopwords">true</str>
    <str name="wt">xml</str>
    <str name="defType">edismax</str>
  </lst>
</lst>

И мой результат был:

<result name="response" numFound="4" start="0">
  <doc>
    <str name="Language">Ingles subtítulos español</str>
    <str name="Title">Footloose</str>
    <arr name="Directors">
      <str>Herbert Ross</str>
    </arr>
    <str name="OriginalTitle">Footloose (1984)</str>
</doc>
  <doc>
    <str name="Language">Ingles subtítulos español</str>
    <str name="Title">Amadeus</str>
    <arr name="Directors">
      <str>Milos Forman</str>
    </arr>
    <str name="OriginalTitle">Amadeus</str>
</doc>
  <doc>
    <str name="Language">Ingles subtítulos español</str>
    <str name="Title">Forrest Gump</str>
    <arr name="Directors">
      <str>Robert Zemeckis</str>
    </arr>
    <str name="OriginalTitle">Forrest Gump</str>
</doc>
  <doc>
    <str name="Language">Doblado al español</str>
    <str name="Title">Chimpancés</str>
    <arr name="Directors">
      <str>Alastair Fothergill</str>
      <str> Mark Linfield</str>
    </arr>
    <str name="OriginalTitle">Chimpanzee Esp</str>
</doc>
</result>

но я хочу этот результат:

<result name="response" numFound="4" start="0">
  <doc>
    <str name="Language">Ingles subtítulos español</str>
    <str name="Title">Footloose</str>
    <arr name="Directors">
      <str>Herbert Ross</str>
    </arr>
    <str name="OriginalTitle">Footloose (1984)</str>
</doc>
  <doc>
    <str name="Language">Ingles subtítulos español</str>
    <str name="Title">Forrest Gump</str>
    <arr name="Directors">
      <str>Robert Zemeckis</str>
    </arr>
    <str name="OriginalTitle">Forrest Gump</str>
</doc>
<doc>
    <str name="Language">Ingles subtítulos español</str>
    <str name="Title">Amadeus</str>
    <arr name="Directors">
      <str>Milos Forman</str>
    </arr>
    <str name="OriginalTitle">Amadeus</str>
</doc>
  <doc>
    <str name="Language">Doblado al español</str>
    <str name="Title">Chimpancés</str>
    <arr name="Directors">
      <str>Alastair Fothergill</str>
      <str> Mark Linfield</str>
    </arr>
    <str name="OriginalTitle">Chimpanzee Esp</str>
</doc>
</result>

Что я должен сделать в своем запросе, чтобы получить ответ, который я хочу??
