elasticsearch - Elastic Search query_shard_exception 执行查询失败

Question

我想要部分搜索 URL，并且我正在使用以下查询:

GET test/_search
{
    "query": {
        "bool": {
            "must": [{
                "query_string": {
                    "query": "*http://localhost:8000/v3/assets/blt5ed2da305d61b2a2/blt10e8f794fa8597d0/5c481035fecde97033721922b/Screenshot_from_2018-07-30_09-53-42.png*",
                    "fields": ["url"],
                    "default_operator": "OR"
                }
            }]
        }
    }
}

我收到以下错误:

                    }
                }
            }
        }]
    },
    "status": 400
}

你能告诉我这里有什么问题吗？我正在使用 query_string 来搜索 URL，但遇到状态为 400 的上述错误。请帮我解决这个问题。

Answer 1

在query string query syntax , 有一些 reserved characters ，即你需要转义的 : 和 /，如下所示:

    "query": "*http\\:\\/\\/localhost\\:8000\\/v3\\/assets\\/blt5ed2da305d61b2a2\\/blt10e8f794fa8597d0\\/5c481035fecde97033721922b\\/Screenshot_from_2018-07-30_09-53-42.png*"
