我正在研究Elasticsearch 1.5.2。我存储了这些产品:" sel 1"," sel 2"," haricot 1"和" haricot 2"
{"@timestamp":"2015-x", "message":"bla", "r":{"analyzed":"blub", "query": {"where":"9999"}}}
{"@timestamp":"2015-x", "message":"blub", "r":{"analyzed":"bla", "query": {"where":"1111"}}}
我做一个查询以获得最便宜的" prix en€/ kg"产品sel和最便宜的" prix en€/ kg"产品扁豆。
POST /test/prod
{
"titre": "sel 1",
"prix en €": 2.49 ,
"prix en €/kg": 5.20
}
POST /test/prod
{
"titre": "sel 2",
"prix en €": 2 ,
"prix en €/kg": 4.3
}
POST /test/prod
{
"titre": "haricot 1",
"prix en €": 14 ,
"prix en €/kg": 0.85
}
POST /test/prod
{
"titre": "haricot 2",
"prix en €": 36 ,
"prix en €/kg": 4
}
有效。现在我想得到" prix en€" (最便宜的" sel" +最便宜的"扁豆")。那我怎么能这样做呢?
