* or a specialised type like <<geo-point,`geo_point`>>, * or a specialised type like <<geo-point,`geo_point`>>,
<<geo-shape,`geo_shape`>>, or <<search-suggesters-completion,`completion`>>. <<geo-shape,`geo_shape`>>, or <<search-suggesters-completion,`completion`>>.
It is often useful to index the same field in different ways for different
purposes. For instance, a `string` field could be <<mapping-index,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 <<analysis-standard-analyzer,`standard` analyzer>>, the
<<english-analyzer,`english`>> analyzer, and the
<<french-analyzer,`french` analyzer>>.
This is the purpose of _multi-fields_. Most datatypes support multi-fields
via the <<multi-fields>> parameter.
