About 24 hours is a reasonable amount of time to wait, but with difficult queries it may take longer. We don't have any experts here on Philipino or Cambodian names and languages, so it's possible that you won't get an answer at all (people won't reply if they don't know the answer, so if you don't get any replies that's why). Everyone who posts here is a volunteer, so reply time will also be affected by whether anyone has time to do any research.
