(1). 创建表结构:

PUT /books
{
  "mappings": {
    "properties": {
      "book_id":    { "type": "integer" },
      "book_name":    { "type": "text" },  
      "book_intr":  { "type": "text"  }, 
      "book_price1":   { "type": "float"},  
      "book_price2":   { "type": "float"},  
      "book_author":   { "type": "keyword"},
      "book_date":   { "type": "date"},
      "book_kind":   { "type": "integer"}
    }
  }
}
结果:
{
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "index" : "books"
}
