各种搜索方式的比较
1、query string search
2、query DSL
3、query filter
4、full-text search
5、phrase search
6、highlight search
搜索全部商品：GET /ecommerce/product/_search
took：耗费了几毫秒
timed_out：是否超时，这里是没有
_shards：数据拆成了5个分片，所以对于搜索请求，会打到所有的primary shard（或者是它的某个replica shard也可以）
hits.total：查询结果的数量，3个document
hits.max_score：score的含义，就是document对于一个search的相关度的匹配分数，越相关，就越匹配，分数也高
hits.hits：包含了匹配搜索的document的详细数据
