index test的 mapping 定义：

"content": {  "type": "text",  "analyzer": "ik_smart" }, "title": {  "type": "text",  "analyzer": "ik_smart" } 

测试分词：

_search 测试一下索引 test

get body

{     "size": 20,     "query": {         "match": {             "content": "广州人"         }     } } 

返回：

{     "took": 0,     "timed_out": false,     "_shards": {         "total": 5,         "successful": 5,         "skipped": 0,         "failed": 0     },     "hits": {         "total": 1,         "max_score": 0.84268904,         "hits": [             {                 "_index": "dcc-speechcrafts",                 "_type": "dcc-speechcraft",                 "_id": "AXIyjmXuVhRXxkRgwNlT",                 "_score": 0.84268904,                 "_source": {                     "title": "",                     "content": "qefdygyrfh 广州人"                 }             }         ]     } } 

第二次_search 测试一下

get body

{     "size": 20,     "query": {         "match": {             "content": "广州"         }     } } 

返回：

{     "took": 1,     "timed_out": false,     "_shards": {         "total": 5,         "successful": 5,         "skipped": 0,         "failed": 0     },     "hits": {         "total": 0,         "max_score": null,         "hits": []     } } 

问题，我那条记录内容包含广州人这三个字，为什么分别用广州人和广州两个词去查询，一次有结果，一次没结果呀？按道理用广州去查询应该也是返回一样的结果的呀，这什么问题？
