如何在elasticsearch中对地理坐标应用filter？
我正在使用elasticsearch和mongoosastic npm模块。 我正在尝试在具有以下模型结构的地理坐标上应用滤镜
geoLocation: { type: { type: String, default: 'Point' }, coordinates: [Number] //orders should be lat,lng } 与映射如下
{ "events": { "settings": { "analysis": { "filter": { "edgeNGram_filter": { "type": "edgeNGram", "min_gram": 1, "max_gram": 50, "side": "front" } }, "analyzer": { "edge_nGram_analyzer": { "type": "custom", "tokenizer": "edge_ngram_tokenizer", "filter": [ "lowercase", "asciifolding", "edgeNGram_filter" ] }, "whitespace_analyzer": { "type": "custom", "tokenizer": "whitespace", "filter": [ "lowercase", "asciifolding" ] } }, "tokenizer": { "edge_ngram_tokenizer": { "type": "edgeNGram", "min_gram": "1", "max_gram": "50", "token_chars": [ "letter", "digit" ] } } } }, "mappings": { "event": { "_all": { "index_analyzer": "nGram_analyzer", "search_analyzer": "whitespace_analyzer" }, "properties": { "title": { "type": "string", "index": "not_analyzed" }, "geoLocation": { "index": "not_analyzed", "type": "geo_point" } } } } } }
询问
{ "query": { "multi_match": { "query": "the", "fields": ["title", ] } }, "filter" : { "geo_distance" : { "distance" : "200km", "geoLocation.coordinates" : { "lat" : 19.007452, "lon" : 72.831556 } } } }
我无法使用以下模型结构在地理坐标上创build索引，我不明白是否不可能使用上面的模型结构来索引地理坐标，因为在我的情况下，坐标的顺序是lat，long，而且我find了某处elasticsearch预计坐标顺序为long，lat。
