"Buffalo“查询无法从/discover端点返回"Buffalo Exchange”

Question

注意到：这个问题专门针对在这里，Developer API的支持人员，因为他们要求freemium用户在堆栈溢出上发布支持问题，而不是试图直接联系他们。如果你不是他们的工作人员，你不能帮忙，或者问题对你不清楚，那就别担心。:)

由于某种原因，/discover端点不返回位于指定坐标处的"Buffalo Exchange"位置，而只返回更远的两个位置。这是我使用的查询：https://discover.search.hereapi.com/v1/discover?at=34.003975%2C-118.484823&q=Buffalo&limit=20&apiKey=<insert API KEY>。以下是我目前所收到的结果：

{
    "items": [
        {
            "title": "Buffalo, NY, United States",
            "id": "here:cm:namedplace:21018816",
            "resultType": "locality",
            "localityType": "city",
            "address": {
                "label": "Buffalo, NY, United States",
                "countryCode": "USA",
                "countryName": "United States",
                "stateCode": "NY",
                "state": "New York",
                "county": "Erie",
                "city": "Buffalo",
                "postalCode": "14202"
            },
            "position": {
                "lat": 42.88544,
                "lng": -78.87846
            },
            "distance": 3551940,
            "mapView": {
                "west": -78.9168,
                "south": 42.82603,
                "east": -78.79492,
                "north": 42.96651
            }
        },
        {
            "title": "Buffalo City, Eastern Cape, South Africa",
            "id": "here:cm:namedplace:23402337",
            "resultType": "locality",
            "localityType": "city",
            "address": {
                "label": "Buffalo City, Eastern Cape, South Africa",
                "countryCode": "ZAF",
                "countryName": "South Africa",
                "state": "Eastern Cape",
                "county": "Buffalo City",
                "city": "Buffalo City",
                "postalCode": "5201"
            },
            "position": {
                "lat": -33.0148,
                "lng": 27.9038
            },
            "distance": 16910944,
            "mapView": {
                "west": 27.15745,
                "south": -33.28749,
                "east": 28.08053,
                "north": -32.674
            }
        }
    ]
}

您可以看到，对于这两个地方，resultType都是"locality"。

现在，将其与搜索术语"Exchange"而不是"Buffalo"的类似查询的第一个结果进行比较。所有其他查询参数都是相同的。这是URL：https://discover.search.hereapi.com/v1/discover?at=34.003975%2C-118.484823&q=Exchange&limit=20&apiKey=<insert API KEY>，结果是这样开始的(由于有很多结果，所以没有完全显示)：

                    ]
                }
            ]
        },
        ...
}

您可以看到，第一个结果的名称是"Buffalo Exchange"，"resultType"是"place"。这就是我想要的结果。问题是，当搜索查询是"Buffalo"？时，为什么不能显示这个结果？当然，对于/discover端点，我不能指定要搜索的类别ID，这只能通过/browse端点获得。但是对于/browse端点，我不能指定一个特定的搜索术语，比如“布法罗”或"Exchange“。

更新：这个问题也发生在加拿大艾伯塔省的“野牛”查询中。对此的查询是https://discover.search.hereapi.com/v1/discover?at=56.745531%2C-111.351341&q=Exchange&limit=20&apiKey=<insert API KEY>。此查询只生成10个结果，其中只有4个具有resultType of "place"。

Answer 1

我们建议应用程序开发人员同时使用自动提示和发现，您可以得到附近的布法罗Exchange，因为Autosuggest认为查询是不完整的。请注意，“发现”认为查询已完成。

在这里，Geocoding和Search的目的是为用户查询提供相关的响应。
