This post demonstrates how to install elasticsearch or kibana plugins behind a proxy. There are several possibilities to achieve an online or offline installation. Following example installs the delete-by-query plugin for elasticsearch v 2.2. It is a great improvement to the previous buggy and non performant implementation. elastic has remove it from the elasticsearch core.

Usually you would install it online the regular way

vinh@cinhtau:/opt/elasticsearch> bin/plugin install delete-by-query

Lets see what the plugin answers
