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

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 models) OR (ethnographic codes))) OR (ethnographic view)) online, volume 1.
• Adding a wildcard symbol may retrieve word variants: ((((ethnographic models) or (ethnographic codes))) or (ethnographic view)) online, volume 1*.
