Note: If you already installed it and show an error then first remove and reinstall again. Maybe it was fixed after that.

Answer 2

Looks like an issue with the elasticsearch configuration, the plugin is required, try this out!

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install analysis-phonetic
sudo service elasticsearch restart

Then try reindexing again.

Answer 3

This means that you need the Smile ElasticSuite plugin. Follow this: https://github.com/Smile-SA/elasticsuite/wiki/ServerConfig-6.x

Answer 4

Its Bit Late But Still Helps lot of people in future

This Error Occurs when your Elasticsearch updates to next release but the [Phonetic & Icu] plugins don't update automatically

Solution

You have to uninstall Previous Version of Plugins

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin remove 
analysis-phonetic
analysis-icu

Install Again so you can get the compatible Version of plugins

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install 
analysis-phonetic 
analysis-icu

Restart Elasticsearch

sudo service elasticsearch restart

Verify it

Answer 5

Expanding on the answer of Waqar Ali:

for the users that use evm (elastic version manager)

if the plugins are missing in the elastic search installation you can install them with the following commands:

cd ~/.evm/elasticsearch 
bin/elasticsearch-plugin install analysis-phonetic
bin/elasticsearch-plugin install analysis-icu
