c# - 巢状查询会传回奇怪的结果。 Elasticsearch

Question

这是我的客户代码:

设置

var defaultSettings = new ConnectionSettings(
    uri: new System.Uri("http://localhost:9200")
);

defaultSettings.SetJsonSerializerSettingsModifier(s => {
    s.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
});

defaultSettings.SetConnectionStatusHandler(c => {
    if(!c.Success) throw new Exception(c.ToString());
});

defaultSettings.SetDefaultIndex("projects");

执行代码

public ActionResult Search(String searchTerm) {
    var result = this.searchClient.Search<ProjectIndexModel>(
        descriptor: new SearchDescriptor<ProjectIndexModel>().Index("projects").AllTypes().Query(
            query: q => q.QueryString(qs => qs.Query(searchTerm)
        )
    ));

    // or
    /* 
    var results = this.searchClient.Search<ProjectIndexModel>(s =>
        s.Index("projects").Type("project").Query(q => 
            q.Term(f => f.ProblemDefinition, searchTerm) || 
            q.Term(f => f.Name, searchTerm) ||
            q.Term(f => f.SuggestedSolution, searchTerm) ||
            q.Term(f => f.Initiator, searchTerm)
        )
    );        
    */

    return Json(result.Documents.ToList());
}

索引在应用程序启动时启动:

foreach(var project in this.dbContext.Projects) {
    var indexModel = Mapper.Map<ProjectIndexModel>(project);
    searchClient.Index(indexModel, "projects", "project", indexModel.Id.ToString());
}

Indexes存在于数据库中(这与我现在的不完全相同，但是架构保持不变)。

我尝试了什么:

Controller 操作返回(默认) 10次命中11个文档的。就像搜索被完全忽略，没有可见错误。
Fiddler对{host:9200}/_search和{host:9200}/projects/project/_search都给出了肯定的结果(命中1个结果)带有查询的POST 请求:

{
    "query": {
        "query_string": {
            "query": "original"
        }
    }
}

有什么问题？

问题不在NEST中。探索了results.ConnectionStatus.ToString()，发现它像Fiddler一样成功后，我发现问题出在我的客户代码中。我忽略了我在未指定POST的情况下发送{searchTerm: $scope.searchTerm}的方法:

$http({
    url: '/projects/search',
    method: "POST",
    data: { searchTerm: $scope.searchTerm }
})
.success(function(data, status, headers, config) {
    $scope.projects = data.documents;
}).error(function(data, status, headers, config) {
    console.log('error: ' + data);
});
