=== Core mapper plugins
|
|
|
|
The core mapper plugins are:
|
|
|
|
<<mapper-size>>::
|
|
|
|
The mapper-size plugin provides the `_size` meta field which, when enabled,
|
|
indexes the size in bytes of the original
|
|
{ref}/mapping-source-field.html[`_source`] field.
|
|
|
|
<<mapper-murmur3>>::
|
|
|
|
The mapper-murmur3 plugin allows hashes to be computed at index-time and stored
|
|
in the index for later use with the `cardinality` aggregation.
|
|
|
|
<<mapper-annotated-text>>::
|
|
|
|
The 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).
