Basic Mapping and Data Types
Introduce the concept of mapping, how Elasticsearch infers data types, and how to define simple explicit mappings for your fields.
Mapping: Your Data's Blueprint
When you put data into Elasticsearch, it needs to understand what kind of data each piece is. This is where mapping comes in.
Mapping is like a schema that defines the fields in your documents and their data types, such as text, numbers, or dates.
Why Mapping Matters
Think of mapping as a blueprint for your search engine. It tells Elasticsearch:
- How to store each field
- How to index (prepare for search) each field
- How each field can be searched and analyzed
Without proper mapping, your searches might not work as expected!
