Elasticsearch Fundamentals: Indexing and Querying Data

# Aggregation
**Aggregation** in Elasticsearch is a powerful feature that allows us to perform data analysis and summarization on our indexed data. It enables us to gather, process, and present insights from our data in a structured and organized manner. Aggregations are similar to SQL's `GROUP BY` clause or data visualization's grouping and aggregation operations.
