At present it is possible to filter total gifts within a query, but there are no options for constituency code. In particular, being able to add a date range to a constituency code would make querying much easier. Example parameters: I want to see people who have given a certain amount of money, but do not have this certain constituency code for this certain year. Right now you can see the gifts they gave in the date range in fine detail, but you can't simultaneously filter their constituency code. Converting our whole coding system over with records as far back as 1990 to use attributes instead seems impractical. More filtering options, please!
