How to index a .PDF file in ElasticSearch

It seems that the elasticsearch-mapper-attachment plugin has been deprecated in 5.0.0 (Released Oct. 26th, 2016). The documentation recommends using the Ingest Attachment Processor Plugin as a replacement.

To install:

sudo bin/elasticsearch-plugin install ingest-attachment

See How to index a pdf file in Elasticsearch 5.0.0 with ingest-attachment plugin? for information on how to use the Ingest Attachment plugin.

You need to check out the elasticsearch-mapper-attachments plugin, as it is very likely to help you achieve what you need.

UPDATE:

This above plugin has been superseded by the ingest attachment processor plugin in ES 5.0
