Persons who work at Company "1" and have an address on "Sesame Street"
Code
// get all persons who work at Company 1
val builder = personBox.query()
.equal(Person_.companyId, 1)
// ...which have an address on "Sesame Street"
builder.link(Person_.addresses).equal(Address_.street, "Sesame Street")
val result = builder.build().find()Result is empty
// get all Person objects
val builder = personBox.query()
// .equal(Person_.companyId, 1) <- without this condition, there are results
// ...which have an address on "Sesame Street"
builder.link(Person_.addresses).equal(Address_.street, "Sesame Street")
val result = builder.build().find()Result with Elmo Person
