Module: SearchMethods::SfxApi

Defined in:
app/controllers/search_methods/sfx_api.rb

Overview

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.
