=== Core mapper plugins
|
|
|
|
The core mapper plugins are:
|
|
|
|
<<mapper-attachments>>::
|
|
|
|
The mapper-attachments integrates http://lucene.apache.org/tika/[Apache Tika] to provide a new field
|
|
type `attachment` to allow indexing of documents such as PDFs and Microsoft Word.
|
|
|
|
<<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.
