elasticsearch最佳实践

创建索引

curl -XPUT http://localhost:9200/book[/code] 
有mapping

如果需要定义每个类型的结构映射，创建type名称为user和blogpost的mapping。

curl -XPUT "http://localhost:9200/book" -d'
{
"mappings": {
"user": {
"_all":       { "enabled": false  },
"properties": {
"title":    { "type": "string"  },
"name":     { "type": "string"  },
"age":      { "type": "integer" }
}
},
"blogpost": {
"_all":       { "enabled": false  },
"properties": {
"id":       { "type": "string"  },
"title":    { "type": "string"  },
"body":     { "type": "string"  },
"created":  {
"type":   "date",
"format": "strict_date_optional_time||epoch_millis"
}
}
}
}
}'


索引文件
添加四个文档

curl -XPOST http://localhost:9200/book/blogpost/1 -d'
{"body":"美国留给伊拉克的是个烂摊子吗"}
'
curl -XPOST http://localhost:9200/book/blogpost/2 -d'
{"body":"公安部：各地校车将享最高路权"}
'
curl -XPOST http://localhost:9200/book/blogpost/3 -d'
{"body":"中韩渔警冲突调查：韩警平均每天扣1艘中国渔船"}
'
curl -XPOST http://localhost:9200/book/blogpost/4 -d'
{"body":"中国驻洛杉矶领事馆遭亚裔男子枪击 嫌犯已自首"}
'


高亮查询
curl -XPOST http://localhost:9200/book/blogpost/_search  -d'
{
"query" : { "term" : { "body" : "中国" }},
"highlight" : {
"pre_tags" : ["<tag1>", "<tag2>"],
"post_tags" : ["</tag1>", "</tag2>"],
"fields" : {
"content" : {}
}
}
}
'


删除索引
curl -XDELETE http://localhost:9200/book[/code]
