I would like to do something like

SELECT * FROM MyTable WHERE input_date >= start_date AND input_date <=
end_date

but I get Inequality Filters Are Allowed On One Property Only

See http://appengine-cookbook.appspot.com/recipe/how-to-query-by-date-range/

Well, guess i'll have to do the script then
