elasticsearch开启脚本及使用

开启script:

Scripting settingsedit

The script.disable_dynamic node setting has been replaced by fine-grained script settings described in the scripting
docs. The following setting previously used to enable dynamic or inline scripts:

script.disable_dynamic: false

It should be replaced with the following two settings in elasticsearch.yml that achieve the same result:

script.inline: on
script.indexed: on

脚本使用，特别注意写法：

curl -XGET 'hm:9200/cars/transactions/_search?search_type=count' -d '

{

    "aggs":{

        "make":{

            "cardinality":{

                "script": "doc[\"make\"].value"

            }

        }

    }

}'

curl -XGET 'hm:9200/cars/transactions/_search?search_type=count' -d '

{

    "aggs":{

        "make":{

            "cardinality":{

                "script": "doc['"'"'make'"'"'].value"

            }

        }

    }

}'

doc[\"dtEventTime\"].date.getHourOfDay()
