6. 测试

// 创建索引
PUT /books
{
  "mappings": {
    "properties": {
      "BookID":    { "type": "integer" },
      "BookName":    { "type": "text","analyzer": "ik_max_word","search_analyzer": "ik_smart","fields":{ "keyword":{"type":"keyword","ignore_above":256}}},  
      "BookPrice":   { "type": "float"},  
      "BookAuthor":   { "type": "keyword"}
    }
  }
}
// 批量插入一些数据
POST _bulk
{ "index" : { "_index" : "books", "_id" : "101" } }
{"BookID":101,"BookName":"C语言程序设计","BookPrice":19,"BookAuthor":"老蒋"}
{ "index" : { "_index" : "books", "_id" : "102" } }
 {"BookID":102,"BookName":"PHP高级编程","BookPrice":29,"BookAuthor":"老李"}

 {"BookID":104,"BookName":"无需流汗和吃苦3天成为java大神","BookPrice":15.5,"BookAuthor":"老张"}
// 用sql语句查询
POST /_sql
{  
   "query": "SELECT * FROM books WHERE BookAuthor = '老王'"
}

 POST /_sql
{  
   "query": "SELECT BookName,BookID FROM books WHERE match(BookName,'我从小就喜欢编程')"
}
