keyword - Поля ключевых слов доступны только по их точному значению.

• [array] - Array support does not require a dedicated type
• [object] - object for single JSON objects
• [nested] - nested for arrays of JSON objects

• [geo-shape] - geo_shape for complex shapes like polygons

• [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
• {plugins}/mapper-murmur3.html[mapper-murmur3]

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 Multi-fields parameter.
