Percolate Query 是先定义检索规则，再把数据读入，找符合检索规则的数据，这样理解正确吗？

下面url请参考  
[https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-percolate-query.html#\_sample\_usage](https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-percolate-query.html#_sample_usage)

先问一个问题，检索的时候只能一条一条检索吗？（也就是一个id一个id的检索吗？）  
GET /my-index/\_search  
{  
"query" : {  
"percolate" : {  
"field": "query",  
"document\_type" : "doctype",  
"index" : "my-index",  
"type" : "message",  
"id" : "1",  
"version" : 1  
}  
}  
}  
如果我的index的某个type里有好多数据，我想一次性全部检索，不可吗？

Percolate Query是用来传递文档（或者现有文档的ID）来检索查询的，一次只有一个文档进行Percolate
