Creating elastic search document by using Alias with Java RestHighLevelClient

Question

I'm trying to create document in elastic search using Alias with the help of Java RestHighLevelClient.

IndexName = items-0 (suffix is indent to increment over time)
Alias = write-inventory-items

I've created this alias to the index. Since I'm planning to update in index name during reindexing, I don't want to depend on the indexName.

Looks like it's a simple use case, but I'm not able to find any way to do it.

Just use the alias instead of the index name in your Java code. For the client, it´s transparent (invisible) if the request-target is an index or alias.

Example:

IndexRequest indexRequest = new IndexRequest("write-inventory-items")
.source("user", "kimchy",
    "postDate", new Date(),
    "message", "trying out Elasticsearch");
