有聚集奇怪的術語，如果另一個映射包含不同類型的同一屬性名稱：Elasticsearch奇怪的術語聚集
MAPPING
{
"mappings" : {
"access" : {
"properties" : {
"cache" : { "type" : "string" }
}
},
"foo" : {
"properties" : {
"foobar" : { "type" : "float" },
"cache" : { "type" : "integer" }
}
}
}
}
批量數據
{"create":{"_type":"foo"}}
{"foobar":[63.8828,66.3633,221.09,736.824,11.4336],"cache":[0,1536000]}
QUERY
curl -XGET "http://localhost:9200/test/access/_search?pretty=1" -d '{

field : "cache",

我不知道爲什麼，當我聚集了空訪問映射我得到這些奇怪的術語......是不是有什麼毛病我的結構或可能是一個錯誤Elasticsearch？
