想不到官方文档还有好几个版本，先看了《Elasticsearch - The Definitive Guide:》，后面再去官网点进去看居然发现内容不一样了，原来是没找对回家的路，应该看这个：
Query-String 方式查询

curl -X GET "localhost:9200/_search?size=5&pretty"
curl -X GET "localhost:9200/_search?size=5&from=5&pretty"
curl -X GET "localhost:9200/_search?size=5&from=10&pretty"
#finds all documents of type `tweet` that contain the word `elasticsearch` in the `tweet` field:
curl -X GET "localhost:9200/_all/tweet/_search?q=tweet:elasticsearch&pretty"
#query looks for john in the name field and mary in the tweet field.
#+name:john +tweet:mary
curl -X GET "localhost:9200/_search?q=%2Bname%3Ajohn+%2Btweet%3Amary&pretty"
#This simple search returns all documents that contain the word mary:
curl -X GET "localhost:9200/_search?q=mary&pretty"
#The name field contains mary or john
#The date is greater than 2014-09-10
#The _all field contains either of the words aggregations or geo
#+name:(mary john) +date:>2014-09-10 +(aggregations geo)
?q=%2Bname%3A(mary+john)+%2Bdate%3A%3E2014-09-10+%2B(aggregations+geo)
