A few days ago I released the first beta version of the elasticshell, a shell for elasticsearch. The idea I had was to create a command line tool that allows you to easily interact with elasticsearch. Isn’t elasticsearch easy enough already? I really do think elasticsearch is already great and really easy to use. However, […]
