What package to import to include || symbol?

[Sanjarbek Amatov]

val q4 = coffees.filter { coffee =>
  List(
      criteriaColombian.map(coffee.name === _),
      criteriaEspresso.map(coffee.name === _),
      criteriaRoast.map(coffee.name === _) // not a condition as `criteriaRoast` evaluates to `None`
  ).collect({case Some(criteria)  => criteria}).reduceLeftOption(_ || _).getOrElse(true: Rep[Boolean])
}

This is a code from slick official documenation, but in my case || symbol not found. What package I need to import?

Solved. In my case one of column field (patient.lastname) was Option type.

val ordersFilterByIdQuery = filterId.map { stringValue =>
  try {
    val intValue = stringValue.toInt
    orders.filter(_.id === intValue)
  } catch {
    case _ => orders
  }
}.getOrElse(orders)
val patientsFilterBySurnameQuery = patients.filter { patient =>
  List(
    filterPatientSurname.map(stringValue => patient.surname.toLowerCase like s"%${stringValue.toLowerCase}%"),
    filterPatientSurname.map(stringValue => patient.firstname.toLowerCase like s"%${stringValue.toLowerCase}%"),
    filterPatientSurname.map(stringValue => patient.lastname.map(lastnameColumn=> lastnameColumn.toLowerCase like s"%${stringValue.toLowerCase}%").getOrElse(false))

  ).collect({ case Some(criteria) => criteria }).reduceLeftOption(_ || _).getOrElse(true: Rep[Boolean])
}

val query = for {
  os <- ordersFilterByIdQuery
  p <- patientsFilterBySurnameQuery if os.patientId === p.id
  d <- doctors if os.doctorId === d.id
  orgs <- organizations if os.organizationId === orgs.id
} yield (os, p, d, orgs)
db.run(query.result)
