在查询自定义创建的＆＃34;知识探索服务时遇到错误＆＃34;

Question

我已根据文档创建了自定义演示。当我在本地托管我的文件时，它会给出以下错误＆＃34; CancellationToken。超时＆＃34！;而且我没有从网络服务获得任何搜索建议。可能是什么问题？

我尽力模仿示例

中给出的语法文件

Search.schema

{
    "attributes":[
        {"name":"ClassCD","type":"string"},
        {"name":"Year","type":"string"},
        {"name":"Keyword", "type":"String", "synonyms":"Keyword.syn"}
    ]
}

Keyword.syn

["class","grade"]
["year","academicyear"]
["year","schoolyear"]

Search.Data

{"ClassCD":"class 1","Year":2018}
{"ClassCD":"class 2","Year":2018}
{"ClassCD":"class 3","Year":2018}
{"ClassCD":"class 4","Year":2018}
{"ClassCD":"class 5","Year":2018}
{"ClassCD":"class 6","Year":2018}
{"ClassCD":"class 7","Year":2018}
{"ClassCD":"class 8","Year":2018}
{"ClassCD":"class 9","Year":2018}
{"ClassCD":"class 10","Year":2018}

语法文件

<grammar root="GetStudents">
    <import schema="search.schema" name="search" />

    <!-- Get Students by Class-->
    <rule id="GetStudents">
        <example>students from class 1</example>
