This kind of failure is complex to figure out especially for existing code bases as one might forget to need to explicitly encode a numeric field in old-style form.

For example as a test, take org.hibernate.search.test.query.facet.Car and remove its reference to @FieldBridge(impl = IntegerBridge.class)) on field cubicCapacity.

Let's see if we can validate such a request and fail fast with a sensible error message.
