如何查询elasticsearch:我一直在获取index_not_found_异常

弹性搜索6.4.3

index_not_found_exception

明确地:

$ curl -X GET "192.168.2.2:9200/MyNew_Index/_search" -H 'Content-Type: application/json'
{
"from": 0,
"size": 40,
"sort":
...

{
    "error": {
        "root_cause": [{
            "type": "index_not_found_exception",
            "reason": "no such index",
            "resource.type": "index_or_alias",
            "resource.id": "MyNew_Index",
            "index_uuid": "_na_",
            "index": "MyNew_Index"
        }],
...

但是,当我查看存在哪些索引时,我会看到:

$ curl -X GET "192.168.2.2:9200/_cat/indices?v" -H 'Content-Type: application/json'
health status index                          uuid                   pri rep docs.count docs.deleted store.size pri.store.size

3322978        1tb        533.4gb

我错过了什么?
