我正在使用ES 5.6 版本。 Kibana（开发工具）中的以下ES查询有效并且提供了匹配。
GET _search
{
"query": { "bool": { "must": {"match": {"name": "UNKNOWN" } }, "must_not": {"regexp": {"failureCause": ".*time exceeded.*"} } } }
}
但是在可视化中，如果我在“过滤器”条件中添加查询，则会出现以下错误。
Error: Request to Elasticsearch failed: {"error":{"root_cause":[{"type":"query_shard_exception","reason":"Failed to parse query [\"query\": {

“ Kibana可视化”（在“过滤器”）选项中的等效查询是什么？谢谢。
