Does IntelliJ support the Jai language? In any case, "M-x helm-projectile-find-file" is the Emacs equivalent of IntelliJ's shift-shift. It's nicely bound to "SPC p f" if you use Spacemacs. You can also search tags (variables, symbols, classes, etc) with "SPC p g". Plus, going for a 3rd party search tool is personal preference, Emacs can also do that. I'm a heavy user of both Spacemacs and IntelliJ, and while the quick search interface of IntelliJ is awesome, Emacs also has this functionality. I assume Jonathan's problem in that video is due to poor language tooling, plus his personal workflow preferences.
