小编Sha*_*ler的帖子

我是Elasticsearch的新手,并且一直在手动输入数据,直到此时为止.例如,我做过这样的事情:

$ curl -XPUT 'http://localhost:9200/twitter/tweet/1' -d '{
    "user" : "kimchy",
    "post_date" : "2009-11-15T14:12:12",
    "message" : "trying out Elastic Search"
}'

我现在有一个.json文件,我想把它编入Elasticsearch.我也尝试过类似的东西,但没有成功:

curl -XPOST 'http://jfblouvmlxecs01:9200/test/test/1' -d lane.json

如何导入.json文件？是否需要先采取步骤以确保映射正确？

我对Elasticsearch很新.我正在尝试编写一个将按字段分组并计算总和的查询.在SQL中,我的查询看起来像这样: SELECT lane, SUM(routes) FROM lanes GROUP BY lane

我在ES中看到这样的数据:
