- Field: A field is a named property within a document. It is analogous to a column in a database table.
- Mapping: A mapping defines the schema of a document type within an index. It specifies the fields and their data types.
Use Cases
Elasticsearch is used in a variety of use cases, including:
- Search: Full-text search, faceted search, and geospatial search.
- Analytics: Real-time analytics, log and event data analysis, and user behavior analysis.
- Data Science: Machine learning, data visualization, and predictive analytics.
