To store minimal required data for each challenge
(Keys) title:<id>, (Keys) end_date:<id>, (Keys) open:<id>, (Sets)
categories:<id>, (Sets) category:<category_name>
To keep track of open and closed challenges

How To Do Efficient Searches
R.sunion(redis_keys)
key1 = {a,b,c,d}
key2 = {c}
key3 = {a,c,e}
sunion {a,b,c,d,e}
R.sinter(redis_keys) # exclusive –
intersect
key1 = {a,b,c,d}
key2 = {c}
key3 = {a,c,e}
sinter {c}
