通过 cloudant-client 访问搜索索引 api

Question

我在 cloudant 服务器中有一个文档为：

 {
  "_id": "web",
  "_rev": "11-b1d0e315272a87c2549df4004d836049",
  "min_weight": 40,
  "max_weight": 65,
  "min_length": 1,
  "max_length": 2.2,
  "attributeCollection": {
    "attributeArray": [
      {
        "updateable": false,
        "lookup": "issuetype",
        "issueAttributeDefinitionId": 13,
        "attributeType": 1,
        "name": "web issue",
        "value": [
          "Improper Neutralization of Input During Web Page Generation"
        ]
      }
    ]
  },
}

我在文档中为 "name" 和 "value" 创建了搜索索引：

function (doc) {
   if (doc.attributeCollection && doc.attributeCollection.attributeArray) {
      for (var i=0; i<doc.attributeCollection.attributeArray.length; i++) {
         if (doc.attributeCollection.attributeArray[i].name) {
            index("name", doc.attributeCollection.attributeArray[i].name, { store : true });
         }
            if (doc.attributeCollection.attributeArray[i].value) {
            for (var j=0; j<doc.attributeCollection.attributeArray[i].value.length; j++) {
               index("value", doc.attributeCollection.attributeArray[i].value[j], { store : true });
            }
         }
      }
   }
}

并且我已在浏览器中成功执行查询 (https://xxx.cloudant.com/issuedb/_design/searchJson/_search/newSearch?limite=10&include_docs=true&q=name:"web*") 以获得结果。此外，我想通过 cloudant-client api 获取结果。下面是我的代码

CloudantClient client=new CloudantClient("xxx", "xxx", "xxx" );
System.out.println("Connection successful! "+client.getBaseUri());
Database db=client.database("issuedb", true);
System.out.println("Datase available - "+db.getDBUri());

List<issue> issues=db.search("searchJson/newSearch")
.limit(10).includeDocs(true)
.query("name=\"web*\"", issue.class);

for (int i = 0; i < issues.size(); i++) {
    issue iss=issues.get(i);
    System.out.println(iss.getId());
    System.out.println(iss.getName());
    System.out.println(iss.getValue());
}

但在浏览器中无法得到搜索查询的结果（数据和索引连接也检查过，没问题）。这段代码有什么错误。

使用 Lucene 查询解析器语法查询搜索索引。尝试使用冒号代替等号：

List<issue> issues=db.search("searchJson/newSearch")
.limit(10).includeDocs(true)
.query("name:\"web*\"", issue.class);
