Mapping base types

Using explicit mapping allows to be faster in starting to insert the data using a schema less approach without being concerned of the field types, so as to achieve better results and performance in indexing, it's required to manually define a mapping.

Fine-tuning mapping brings some advantages such as:

• Reducing the index size on the disk (disabling functionalities for custom fields)

• Indexing only interesting fields (general speed up)

• Precooking data for fast search or real-time analytics (such as facets)

• Correctly defining whether a field must be analyzed in multiple tokens or considered as a single token

Elasticsearch allows using base fields with a wide range of configurations.

Getting ready
