in reply to Efficient search through a huge dataset

I don't have solution at this point, but we will be sure if this is exactly what you desire.

  • A:Are you trying to find out whether your second file is a subset of first file?
  • Or B: Find (also) the records in the second file which are not in the first file?

      B. Actually for each record in the second file, I'd like to mark it 1/0 depending on whether it's in the first.
