创建指定索引和mapping

curl  -u 'elastic:password' -X PUT  'http://$es:9288/index_test1'  -H 'Content-Type: application/json' -d '{
"mappings" : {
"properties" : {
"adzoneId" : {
"type" : "keyword"
},
"adzoneName" : {
"type" : "keyword"
},
"alimamaRate" : {
"type" : "float"
}}
}

添加一条mapping字段

curl  -X PUT  'http://{es}:9288/test_yxd/_mapping'  -H 'Content-Type: application/json' -d '

"clickTime" : {
"type" : "date",
"format" : "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis",
"ignore_malformed" : true
}
}
}'
