What Elasticsearch Does
Elasticsearch provides fast, scalable search and analytics capabilities. It can index and search large volumes of data quickly, making it ideal for applications that need to search through documents, logs, or any structured or unstructured data.
How Elasticsearch Works
Elasticsearch operates through a distributed architecture:
1. Indexing: Documents are stored in indices (similar to databases)
2. Sharding: Data is distributed across multiple nodes
3. Replication: Copies are maintained for reliability
4. Search: Queries are executed across the cluster
5. Aggregation: Data can be analyzed and summarized
