Elasticsearch无法返回某些文档

我有这些数据：

{"_index": "simple", "_type": "motorcycle", "_source": {"date": "2018-04-28T13:16", "price": 59900, "sellerName": "Lelles MC AB", "description": "KTM 690 Duke (Abs) M\u00e4tarst\u00e4llning: 450 mil F\u00e4rg: Vit Typ: Touring/Landsv\u00e4g Info: Mycket fin Duke 690 med rensad bakdel och handskydd.", "location": "Uppsala", "id": 345, "title": "KTM 690 Duke (Abs)", "modelYear": 2016, "url": "https://www.blocket.se/uppsala/KTM_690_Duke__Abs__79079911.htm?ca=11&w=3", "vehicleType": "Touring"}}

我正在运行这个python代码来索引它：

    def create_index(self, file_path):
        """
            Takes path to file containing JSON-formatted data
            and indexes into Elasticsearch index.
        """
        print('Creating index "{}"'.format(INDEX_NAME))

        request_body = {
"settings":{
    "index":{
        "number_of_shards":1,
        "number_of_replicas":0
    }
},
"mappings":{
    "motorcycle":{
        "properties":{
            "location": {
                "type":"text",
                "analyzer":"swedish"
            },
            "description":{
                "type":"text",
                "analyzer":"swedish"
            }
        }
    }
}
        }
        self.es.indices.create(index = INDEX_NAME, body = request_body)
        f_in = open(PATH_TO_DATASET, "r")
        actions = (json.loads(line) for line in f_in)
        print("Performed bulk index: {}".format(bulk(self.es, actions)))
        self.es.indices.refresh(index = "simple")

现在，我尝试使用postman查询索引，查找所有带location:Uppsala的文档（第一个对象的位置（我使用python进行相同的查询，结果相同）：

POST to localhost:9200/simple/_search:
{
    "query": {
        "bool": {
            "filter": [

                {
                    "term": {
                        "location": "uppsala"
                    }
                }
            ]
        }
    }
}

它什么都不返回。如果我将位置更改为uddevalla，同样的事情也会发生，这也是原始数据（第二个文档）。

但是，如果我将location更改为norrköping，则会返回第三个文档，它应该执行此操作。

这种不稳定行为背后的原因是什么？

更新：尝试使用稍大的数据文件：

查询värmdö会返回正确的文档。查询karlstad不返回任何内容（应该返回1次）。查询＆＃34; helsingborg＆＃34;返回正确的文件。

更新2：

当它们看起来似乎没有显示任何查询时，不会显示的文档。例如，此查询：

{
    "query": {
        "bool": {
            "filter": [],
            "must": {
                "multi_match": {
                    "fields": [
                        "title^1.0",
                        "description"
                    ],
                    "operator": "or",
                    "query": "suzuki",
                    "type": "cross_fields"
                }
            }
        }
    }
}

只会返回一个结果（location:Värmdö的结果），而事实上它应该返回两个（location:Karlstad未返回的结果）。

将索引创建代码更改为此解决了问题。
