1. What is Elasticsearch and how does it work?
   Answer: Elasticsearch is a distributed search engine based on Apache Lucene. It stores JSON documents and allows fast indexing and full-text search through RESTful APIs. It uses indices, shards, and nodes to scale horizontally.

2. What is the difference between term and match queries?
   Answer:

   • Term queries match exact terms and are used for keyword fields.

   • Match queries analyze text using an analyzer and are suitable for full-text search on text fields.

3. How does Elasticsearch handle replication and fault tolerance?
   Answer: Elasticsearch uses primary and replica shards. Each document is indexed into a primary shard, and replicas provide redundancy and allow parallel searching. If a node fails, a replica takes over automatically.

4. What are mappings in Elasticsearch?
   Answer: Mappings define the structure of documents and data types for fields within an index. It is similar to schema in relational databases but more flexible.

5. How do aggregations work in Elasticsearch?
   Answer: Aggregations group and summarize data. Bucket aggregations group documents (e.g., by date or term), while metric aggregations calculate stats like sum, average, and max.

6. What is Elasticsearch Query DSL?
   Answer: The Query DSL is Elasticsearch’s JSON-based language for defining complex queries. It supports filtering, full-text search, relevance tuning, and combining multiple conditions.

7. How can Elasticsearch be secured?
   Answer: Security features include TLS encryption, API key or basic authentication, role-based access control (RBAC), and audit logging. Elastic Stack's security features can be enabled for free with Elastic’s Basic license.

8. What is the difference between shards and nodes?
   Answer: A node is a single instance of Elasticsearch, while a shard is a subdivision of an index. Shards are distributed across nodes to enable scalability and parallel processing.

9. How do you monitor Elasticsearch performance?
   Answer: Use tools like Kibana Monitoring, APIs (_cluster/health, _cat/indices), Prometheus exporters, and Elastic’s Stack Monitoring to monitor resource usage, indexing rates, and search latencies.

10. Can Elasticsearch be used for analytics?
    Answer: Yes. Elasticsearch supports real-time analytics using aggregations, Kibana dashboards, and even integration with BI tools. It is widely used for monitoring, metrics analysis, and anomaly detection.
