Filter Logic

[jbmattos]

Main problem to address with the filters:
The UHRI database is enormous. The filters should restrict the volume of data loaded to the page in order to provide a satisfactory user experience.

The current UHRI filter logic is as follows:

• The values populating the filters are all unique values on the UHRI database and the filters are independent of each other.
• Multiples values of the filters can be selected
• It is required at least 1 selected Country, but the other filters remain optional.

Problems:

1. The Region filter (e.g. Africa, Asia-Pacific) encompasses a wider data scope compared to the Country filter. It is inconsistent to require the latter to restrict data but allow multiple choices of the first.
2. Because the filters' values are independent of each other, the selection of one filter may undo the other's restrictions. May be interesting to condition the values populating some filters to the restrictions already selected by the user.
