This is going to be so awesome. ES UI tables break whenever & is filtered on using =.

@chandlerprall is there anything I can do to help get this over the line?

[chandlerprall]

@naderhen thanks for the reminder :) I was out last week, but am back to working on this.

Just pushed a refactor of the change to maintain backwards compatibility, better parsing, and correct pretty value printing of these values. Also added a unit test. Remainder of work is to validate the generated ES query string & DSL is correct. I should have this in a completed state soon.
