OpenSearch is a community-driven, open-source fork of Elasticsearch and Kibana. Developers who are curious about how search in OpenSearch works will be welcome in this session. Finding a four-pawed friend to adopt can be challenging. If you live in a small flat, you may have some requirements regarding the size of pet you can accommodate. But can OpenSearch assist you in this search? We will try! In this talk, we will learn how to write and run search queries on our OpenSearch cluster with the purpose to find your future friend. We will cover the most common queries from term-level, full-text queries and boolean queries. We will be playing with an interesting pet dataset and the Python OpenSearch client.

Best practices for scaling Elasticsearch clusters

• Use metrics from inside Elasticsearch for accuracy
• Scale in larger increments to reduce noise
• Force index rotation to evenly spread load across nodes
• Judge cluster size based on disk usage and search latency
• Use local SSDs for better I/O latency
• Consider hot-warm-cold architecture for data management
