best practices for querying a resource

[tyty]

I have a resource called Resturants. There are multiple fields and a few i want to allow people to query specifically for (Rating and Location). 

Is it better to create multiple RPC endpoints like:

```
//all resturants
QueryReseturants(QueryResturantsRequest) returns (QueryResturantsResponse)

// all resturants with a specific rating
QueryResturantsByRating(QueryResturantsByRatingRequest) returns (QueryResturantsByRatingResponse)

// all resturants with a specific locatoin

QueryResturantsByLocation(QueryResturantsByLocationRequest) returns (QueryResturantsByLocationResponse)

```

OR is it better to have one query, with the specifics as fields:

```

//all resturants
QueryReseturants(QueryResturantsRequest) returns (QueryResturantsResponse)

```

where QueryResturantsRequest contains a Rating and Location field. Specifying neither will return all. or you can specify one or both of the fields to narrow down the resturants returned.

Either way works for our use case, but I'm mainly curious if this breaks protobuf standards or something like that.

Thanks.

I think this question is more suited for gRPC, protobuf doesn't have standards about RPC endpoints.
