descendant searches

[lonnylundsten]

Please add the ability to search for concept plus descendants. Currently we can only search by one concept, however, moving forward we would like to search by concept with the ability to include descendants.

As an example, I would like to search for all images of trash, including all descendants.

trash

- abandoned research equipment
- cloth
- concrete
- glass
- leather
- manufactured wood
- metal
- paper
- plastic
- rope
- rubber
