Add example with rest filtering

[mispp]

When you get a collection like /stars, but I want to filter ones which have a name like '%food%'

Something like /stars/?name-contains=food

Thanks for the issues! This is definitely something that will fit in here, I'll want some sort of search endpoint eventually. I'm going to be building this app slowly, so it may be a while before I get to it.
