ElasticSearch返回所有文件

Question

這裏是我發送給ElasticSearch查詢：

http://localhost:9200/user-index/user/_search/?queryb%5Bname%5D=Richard 

返回JSON是這樣的：

{ 
    "hits": [ 
    { 
     "_index": "user-index", 
     "_type": "user", 
     "_id": "WgrvE-DzQJminNreBIsRNA", 
     "_score": 1.0, 
     "_source": { 
     "name": "Richard", 
     "db_id": "7" 
     } 
    }, 
    { 
     "_index": "user-index", 
     "_type": "user", 
     "_id": "GwMOuYbUR8y48RrG4HgXdg", 
     "_score": 1.0, 
     "_source": { 
     "name": "John", 
     "db_id": "8" 
     } 
    }, 
    { 
     "_index": "user-index", 
     "_type": "user", 
     "_id": "C-bgK3pNTNiX9Cz0x8EftA", 
     "_score": 1.0, 
     "_source": { 
     "name": "Harold", 
     "db_id": "2" 
     } 
    } 
    ] 
} 

只有那些真正的比賽之一。爲什麼把它們全部發回來？

Answer 1

Elasticsearch返回索引用戶索引中具有類型用戶的所有記錄，因爲它無法找到搜索查詢。搜索查詢應指定爲查詢字符串the parameter "q"或a request body。

嘗試http://localhost:9200/user-index/user/_search?q=name%3ARichard
