Apache Solr nGram分组问题

Question

我将ngram分组时遇到问题。我的查询是

http://localhost:8983/solr/archiveCore/select?group.field=strSO&group=true&q=strSO%3A*&rows=2147483647&start=0&wt=json&indent=true&fl=strSO

它在

之类的网络浏览器（chrome）中向我显示正确的结果

{
  "responseHeader":{
    "status":0,
    "QTime":51,
    "params":{
      "q":"strSO:*",
      "indent":"true",

              {
                "strSO":"EV12648-02"}]

但是在Java中不起作用。我将查询放在我的项目jquery中，而ngram什么也没显示。我不明白为什么它什么都没给我显示。它在网络浏览器上运行良好。

这是我的用于配置ngram的schema.xml

<fieldType name="text_ngram" class="solr.TextField" positionIncrementGap="100" stored="false" multiValued="true">
<analyzer type="index">
<tokenizer class="solr.NGramTokenizerFactory" minGramSize="2" maxGramSize="20"/>    
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.EdgeNGramTokenizerFactory" minGramSize="2" maxGramSize="20"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>

任何人都可以帮助我解决此问题吗？

这是我的jquery代码

<script>

var URL_PREFIX = "http://localhost:8983/solr/archiveCore/select?q=strSO:*";
var URL_SUFFIX = "&group.field=strSO&group=true&rows=2147483647&start=0&wt=json&indent=true&fl=strSO";

$.ajax({

success : function(data) {
var docs = JSON.stringify(data.response.docs);
var jsonData = JSON.parse(docs);
