Perhaps you should try some spelling variations:
ethnographic video » ethnographic videos, ethnographic view, ethnographic index
ethnographic codes » ethnographic models, ethnographic notes, ethnographic scales
ethnographic mode » ethnographic models, ethnographic moment, ethnographic notes

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((ethnographic video) OR (ethnographic mode))) OR (ethnographic codes)) online, volume 1.
• Adding a wildcard symbol may retrieve word variants: ((((ethnographic video) or (ethnographic mode))) or (ethnographic codes)) online, volume 1*.
