Good question. The first decent idea that came to mind was searching
through a cartesian join of all diseases & symptoms:
{ (disease1, symptom1),
  (disease1, symptom2),
  (disease2, symptom1),
  (disease2, symptom2) }

Searching for (flu, runny_nose) would not find anything (given the
sample data in your original message) so you could rule out flu.
