Setup Elasticsearch

Prepare Elasticsearch:

• Install Elasticsearch on your machine and start it.
• By default, Elasticsearch listens on port 9200 for HTTP requests. You can access it via http://localhost:9200/ in your web browser or use tools like curl or Postman to interact with it.
• The Elasticsearch documentation is an excellent resource for learning about the API and its capabilities: Elasticsearch Reference.

Install elasticsearch dependency:

go get -u github.com/elastic/go-elasticsearch/v8
