### 1.The remote cluster verifies the index alias
Hello, when you use Java API Client to verify the remote cluster alias, this alias index exists in the remote cluster,
However, the API interface returns false and does not exist
When using Kibana to test the remote cluster alias index, you can get the data as follows:
#### 1.1 request
```elm
GET /normal-combind-1084,HFZQ-FZ-Elasticsearch:normal-combind-1084/_search?ignore_unavailable=true
{
"size": 0,
"aggs": {
"agent_names": {
"terms": {
"field": "agent.name",
"size": 100000
}
}
}
}
```
#### 1.2 return
```elm
{
"took": 34,
"timed_out": false,
"_shards": {
"total": 2,
"successful": 2,
"skipped": 0,
"failed": 0
},
"_clusters": {
"total": 1,
"successful": 1,
"skipped": 0
},
"hits": {
"total": {
"value": 10000,
"relation": "gte"
},
"max_score": null,
"hits": []
},
"aggregations": {
"agent_names": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "fzrdsj61-81.hfzq.local",
"doc_count": 76919
},
{
"key": "fzrdsj61-82.hfzq.local",
"doc_count": 68178
},
{
"key": "fzrdsj61-92.hfzq.local",
"doc_count": 51231
},
{
"key": "fzrdsj61-93.hfzq.local",
"doc_count": 49505
},
```
#### 1.3 Verify the remote alias index
```elm
GET /HFZQ-FZ-Elasticsearch:*/_alias/normal-combind-1084
return :
{
"error": "alias [normal-combind-1084] missing",
"status": 404
}
```
How Do I Obtain the Existence of a Remote Cluster Alias Index?
