1. Simple HTTP call to _search REST API of Elastic
• No Elasticsearch client library – only HTTP rest api calls
• Using internal (your) programming language http library
• All logic, maintenance and compatibility is on you
• Small app, low number of searches
• Usually simple queries
Good for small apps, rare searches, low search throughput
