How to apply filtering for model dynamic field

[dchaitanya]

I have dynamic field name, constructed based on combination for two or more model field values. Now if I want to apply filter on this field, is it possible to apply by passing any column def argument like lookup_field or any other.

I want to pass search value = model.filed1 or model.filed2 or model.field3

Interesting suggestion, but not supported now. I will leave this issue open; I'm willing to accept PR on this
