# Mapper annotated text plugin [mapper-annotated-text]
|
|
|
|
::::{warning}

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

The mapper-annotated-text plugin provides the ability to index text that is a combination of free-text and special markup that is typically used to identify items of interest such as people or organisations (see NER or Named Entity Recognition tools).
|
|
|
|
The elasticsearch markup allows one or more additional tokens to be injected, unchanged, into the token stream at the same position as the underlying text it annotates.
