Query is undefined in controller

[OisinFoley]

Hi all,

Thanks for the great work so far! - Having trouble getting this to work.
I installed the package, made my component searchable and then used the code snippet from this controller file on master.

However, when the incoming request comes in, the if (ctx.query._q) { expression causes a crash, becase the query prop is undefined on the ctx object.

Any advice on how I can fix this?
