nit: can you just omit the URL? and maybe add a route for search?

[dpapad, 2016/07/01 21:59:42]

The 'url' field is needed only for the Compiler. I prefer not to deal with
routing in this CL, but the goal is to add routing for searching in follow up CL
(after the core logic is completed).

[Dan Beam, 2016/07/01 22:41:01]

fun fact: it's only required if you:
a) depend settings_router and actually get the @typedef (otherwise it's silently
ignored, oh yay!)
b) land before my CL to make it optional ;)[1]

or dschuyler@'s CL that makes url: (string|undefined), that'd also help ;)
