This works:

testSelectWithAnd
	| found |
	repository
		do: [ self addDummyPeople.
			found := DummyPerson
				findOne: [ :each | each firstName = 'john' & (each lastName = 'q4') ].
			self assert: found notNil.
			self assert: found firstName equals: 'john'.
			self assert: found lastName equals: 'q4' ]
