module SearchMethods
  
  # NON-WORKING sketch of a search method that contacts SFX api directly.
  # Problem with this was that SFX is way too slow; SFX api didn't take
  # account of year/volume/issue when displaying multiple results anwyay,
  # so there wasn't that functionality benefit. It just wasn't worth it. 
  #
  # This code is basically copied and pasted from before the refactor,
  # it's not close to working yet, but is left for archival purposes
  # in case anyone wants to take a stab at it.
