Taxonomy terms as numbers? Creating real estate website, i have a lot of exposed filters.
For year when the object is built i have number field which in views is as exposed filter.
When user makes input he puts year 1961 for example.

User searching in exposed filter writes 1961 and filter is set up like "equal or higher" so he gets all objects made 1961 and higher. Works fine.

But i have a problem with floors.
For floors i have vocabulary:
ground floor
1
2
3
4
etc..
attic

I cant use number field because of ground floor and attic so i had to use taxonomy.
But now i cant use equal or higer as exposed filter so if user picks number 3 he only gets appartments with 3 floors.
You could still use floors as numeric field, having numbers as keys and display output as needed.

Example of "List (integer)" values:


-1|Basement
0|Ground floor
1|1
2|2
3|3
100|Attic



This would allow you the same logic for floors.

EDIT:
When selecting the field as a filter in Views you need to choose the delta value. It looks something like Content: Floors (field_floors:delta). This will give you the integer filter options such as Is greater than or equal to.
