Elasticsearch match_phrase用法

目前有用到的用法如下：

 1 post /index_name/_search
 2 {
 3   "query" : {
 4     "match_phrase": {
 5       "nickname": {
 6         "query": "nihao ma",
 7         "slop" : 0
 8       }
 9     }
10   },
11   "size" : 10,
12   "from" : 0
13 }

通过from+size来实现分页，但是有个限制，from+size不能超过index.max_result_window。

slop参数其实就是你允许你输入的词里面中间还能隔着几个词。也就是说，slop=0就是只能按你输入的词来搜索。slop=1，比如输入是“ni ma", 那么结果里可能就包含"ni ba ma"。
