我正在使用Elasticsearch 2.1。我不太清楚自己在做什么错。它使我困惑查询，过滤器之间的区别…您能帮我吗？

我正在尝试执行此查询。它返回一个空结果：

curl -XGET 'http://ESNode01:9201/living_team/inputs/_search?pretty' -d '
{
    "query": {
        "filtered": { 
            "query": { "match_all": {} },
            "filter": { "term": { "channel": "Feina" } }
        }
     }
}
'

但是，当我执行不带过滤器的查询时，它将返回所有内容：

curl -XGET 'http://ESNode01:9201/living_team/inputs/_search?pretty' -d '
{
    "query": {
        "filtered": { 
            "query": { "match_all": {} },
        }
     }
}
'

这是一个文档样本：
