ES错误“原因”：“意外字符（'\“'（代码34）

Question

当我尝试运行以下ES查询时，出现错误：

查询：

curl  http://localhost:9200/test1/_search -H 'Content-Type: application/json' -d'
{
    "size": 500
    "query": {
        "bool": {
            "must": {},
            "filter": {
                {
                    "multi_match": {
                        "type": "best_fields",
                        "query": "10.9.5.8 10.9.0.7 10.9.5.5 10.9.2.3 10.9.2.1",
                        "lenient": true
                    }
                }
            }
        }
    }
}

我得到的错误是：

{"error":{"root_cause":[{"type":"json_parse_exception","reason":"Unexpected character ('\"' (code 34)): was expecting comma to separate Object entries\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@3667826c; line: 4, column: 6]"}],"type":"json_parse_exception","reason":"Unexpected character ('\"' (code 34)): was expecting comma to separate Object entries\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@3667826c; line: 4, column: 6]"},"status":500}
