== Creating indexes, alias and reindexing using Elasticsearch API
2+
3+
In the following steps, we are going to, manually and using `Elasticsearch` API, create an index called `ecommerce.products.v1`, associate an alias called `ecommerce.products` for it and then reindex to another index called `ecommerce.products.v2`.
4+
5+
Make sure you have a clean `Elasticsearch` without the indexes and alias mentioned previously. Also, the following `curl` commands must be executed in `springboot-elasticsearch-thymeleaf` root folder.
