date

Boolean datatype

boolean

Binary datatype

Range datatypes

integer_range, float_range, long_range, double_range, date_range

[](#_complex_datatypes)Complex datatypesedit

Array datatype

Array support does not require a dedicated type

Object datatype

Nested datatype

[](#_geo_datatypes)Geo datatypesedit

Geo-point datatype

geo_point for lat/lon points

Geo-Shape datatype

geo_shape for complex shapes like polygons

[](#_specialised_datatypes)Specialised datatypesedit

mapper-annotated-text

Percolator type

join datatype

Defines parent/child relation for documents within the same index

Alias datatype

Defines an alias to an existing field.

[](#_multi_fields)Multi-fieldsedit

It is often useful to index the same field in different ways for different purposes. For instance, a string field could be mapped as a text field for full-text search, and as a keyword field for sorting or aggregations. Alternatively, you could index a text field with the standard analyzer, the english analyzer, and the french analyzer.

This is the purpose of _multi-fields_. Most datatypes support multi-fields via the fields parameter.
