Use with server APIs

Hey there,
Loved the demo GIF. Can this be used with REST APIs as query parameters in any way? e.g.
```
my-api.com/products?first_name=John&last_name=Doe
```

where ```first_name = John``` and ```last_name = Doe``` are the query parameters.
I imagine that it might be possible with some tweaking.

No files or tests are named in the issue. Start by reading the repository's consumer API and tracing how filters are represented and emitted, then determine the intended query-parameter contract from the example. Done should be defined as a documented, tested way to use the filter with REST API query parameters.
