Field datatypes
editField datatypes
editElasticsearch supports a number of different datatypes for the fields in a document:
Core datatypes
edit- String datatype
-
string
- Numeric datatypes
-
long
,integer
,short
,byte
,double
,float
- Date datatype
-
date
- Boolean datatype
-
boolean
- Binary datatype
-
binary
Complex datatypes
edit- Array datatype
-
Array support does not require a dedicated
type
- Object datatype
-
object
for single JSON objects - Nested datatype
-
nested
for arrays of JSON objects
Geo datatypes
edit- Geo-point datatype
-
geo_point
for lat/lon points - Geo-Shape datatype
-
geo_shape
for complex shapes like polygons
Specialised datatypes
edit- IPv4 datatype
-
ip
for IPv4 addresses - Completion datatype
-
completion
to provide auto-complete suggestions - Token count datatype
-
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 - Attachment datatype
-
See the
mapper-attachments
plugin which supports indexingattachments
like Microsoft Office formats, Open Document formats, ePub, HTML, etc. into anattachment
datatype.
Multi-fields
editIt is often useful to index the same field in different ways for different
purposes. For instance, a string
field could be indexed as
an analyzed
field for full-text search, and as a not_analyzed
field for
sorting or aggregations. Alternatively, you could index a string 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.
