curl -X POST http://118.190.87.198:9200/_analyze?pretty -H 'Content-Type:application/json' -d '{  "analyzer": "ik_smart",  "text": "山东省济南市天桥"}'

安装 head 插件

https://chrome.google.com/webstore/search/ElasticSearch%20Head?utm_source=chrome-ntp-icon

创建索引：curl -XPUT http://118.190.87.198:9200/index2

增加测试数据：
curl -X POST http://118.190.87.198:9200/index/xw/1 -H 'Content-Type:application/json' -d '{"content":"美国留给伊拉克的是个烂摊子吗"}'

curl -X POST http://118.190.87.198:9200/index/xw/2 -H 'Content-Type:application/json' -d '{"content":"公安部：各地校车将享最高路权"}'

curl -X POST http://118.190.87.198:9200/index/xw/3 -H 'Content-Type:application/json' -d '{"content":"中韩渔警冲突调查：韩警平均每天扣1艘中国渔船"}'

curl -X POST http://118.190.87.198:9200/index/xw/4 -H 'Content-Type:application/json' -d '{"content":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"}'

curl -X POST http://118.190.87.198:9200/index/xw/5 -H 'Content-Type:application/json' -d '{"content":"作为一个发展中的国家还是要好好努力的"}'

head插件的复合：
{ "query" : { "match" : { "content" : "中国" }}, "highlight" : { "pre_tags" : ["<tag1>", "<tag2>"], "post_tags" : ["</tag1>", "</tag2>"], "fields" : { "content" : {} } } }
