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"。
