Solr.Net中的邻近度 - 没有结果

Question

如何在solr.net中执行此简单查询？我现在已经3个小时......

Text:"Thank you"~10

以下不会返回结果：

var query = new SolrQueryByField("Text", "\"Thank you\"~10");

来自Fiddler：

GET /solr/new_core/select?rows=10&q=Text%3a%22%5c%22Thank+you%5c%22%5c%7e10%22&? HTTP/1.1

来自 schema.xml ：

<field name="Text" type="text_auto" indexed="true" termVectors="true" stored="true" required="true" multiValued="false" />

<fieldType class="solr.TextField" name="text_auto" positionIncrementGap="100">
  <analyzer>
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.ShingleFilterFactory" maxShingleSize="4" outputUnigrams="true"/>
  </analyzer>
</fieldType>
