On a side node, do we really need 'of()'. Sure it makes it sounds a little more like real English, but then why is there no 'and()' between lat and long.
The whole DSL part only carries so far when directly hosted in Java. If there is no compelling reason for 'of()' i would argue one can drop it.

what's about 'proximity' instead of 'spatial'?

			builder
				.spatial()
					.onFields(long, lat)
					.within( 51, Unit.KM )
						.of().latitude( 24d ).longitude( 31.5d )
					.createQuery();
