Field datatypesedit

Elasticsearch supports a number of different datatypes for the fields in a document:

Core datatypesedit

string
text and keyword
Numeric
long, integer, short, byte, double, float, half_float, scaled_float
Date
date
Date nanoseconds
date_nanos
Boolean
boolean
Binary
binary
Range
integer_range, float_range, long_range, double_range, date_range

Complex datatypesedit

Object
object for single JSON objects
Nested
nested for arrays of JSON objects

Geo datatypesedit

Geo-point
geo_point for lat/lon points
Geo-shape
geo_shape for complex shapes like polygons

Specialised datatypesedit

IP
ip for IPv4 and IPv6 addresses
Completion datatype
completion to provide auto-complete suggestions
Token count
token_count to count the number of tokens in a string
mapper-murmur3
murmur3 to compute hashes of values at index-time and store them in the index
mapper-annotated-text
annotated-text to index text containing special markup (typically used for identifying named entities)
Percolator
Accepts queries from the query-dsl
Join
Defines parent/child relation for documents within the same index
Alias
Defines an alias to an existing field.
Rank feature
Record numeric feature to boost hits at query time.
Rank features
Record numeric features to boost hits at query time.
Dense vector
Record dense vectors of float values.
Sparse vector
Record sparse vectors of float values.

Arraysedit

In Elasticsearch, arrays do not require a dedicated field datatype. Any field can contain zero or more values by default, however, all values in the array must be of the same datatype. See Arrays.

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.
