我已经创建了索引并将其作为示例教程的索引,在这里......
https://www.elastic.co/guide/en/elasticsearch/reference/2.0/geo-point.html
具体写作如下:
curl -PUT 'localhost:9200/my_index?pretty' -d '
{
"mappings": {
"my_type": {
"properties": {
"location": {
"type": "geo_point"
}
}
}
}
}'
我还添加了两点作为数据
curl -PUT 'localhost:9200/my_index/my_type/1?pretty' -d'
{
"text": "first geo-point",
"location": {
"lat": 41.12,
"lon": -71.34
}
}'
curl -PUT 'localhost:9200/my_index/my_type/1?pretty' -d'
{
"text": "second geo-point",
"location": {
"lat": 41.13,
"lon": -71.35
}
}'
页面上的示例地理边界框查询起作用(即):
curl -XGET 'localhost:9200/my_index/_search?pretty' -d'
{
"query": {
"geo_bounding_box": {
"location": {
"top_left": {
"lat": 42,
"lon": -72
},
"bottom_right": {
"lat": 40,
"lon": -74
}
}
}
}
}'
但是此页面中的示例(https://www.elastic.co/guide/en/elasticsearch/reference/2.0/query-dsl-geo-bounding-box-query.html)无效:
我尝试过的内容如下:
curl -XGET 'localhost:9200/my_index/_search?pretty' -d'
{
"bool" : {
"must" : {
"match_all" : {}
},
"filter" : {
"geo_bounding_box" : {
"my_type.location" : {
"top_left" : {
"lat" : 42,
"lon" : -72
},
"bottom_right" : {
"lat" : 40,
"lon" : -74
}
}
}
}
}
}'
我得到的错误如下:
"error" : {
"root_cause" : [ {
"type" : "search_parse_exception",
"reason" : "failed to parse search source. unknown search element [bool]",
"line" : 3,
"col" : 5
} ],
"type" : "search_phase_execution_exception",
"reason" : "all shards failed",
"phase" : "query",
"grouped" : true,
"failed_shards" : [ {
"shard" : 0,
"index" : "my_index",
"node" : "0qfvkynhTRyjHFRurBLJeQ",
"reason" : {
"type" : "search_parse_exception",
"reason" : "failed to parse search source. unknown search element [bool]",
"line" : 3,
"col" : 5
}
} ]
},
"status" : 400
}
我希望它只是一个简单的错误,所以想知道我做错了什么?
答案 0 :(得分:6)
您需要指定整个事情是一个查询:
curl -XGET 'localhost:9200/my_index/_search?pretty' -d'
{
"query": {
"bool" : {
"must" : {
"match_all" : {}
},
"filter" : {
"geo_bounding_box" : {
"my_type.location" : {
"top_left" : {
"lat" : 42,
"lon" : -72
},
"bottom_right" : {
"lat" : 40,
"lon" : -74
}
}
}
}
}
}
}'
但据我所知,使用bool with must和filter是旧的做事方式。在以前的版本中,地理查询被认为是"过滤器",因此您必须首先运行match_all查询以返回所有结果,然后使用地理边界框进行过滤。在Elasticssearch 2.0+中,过滤器和查询之间没有分离 - 一切都是查询。因此,您可以直接运行地理查询:
curl -XGET 'localhost:9200/my_index/_search?pretty' -d'
{
"query": {
"geo_bounding_box": {
"location": {
"top_left": {
"lat": 42,
"lon": -72
},
"bottom_right": {
"lat": 40,
"lon": -74
}
}
}
}
}'
