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

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 videos) OR (((ethnographic codes) OR (ethnographic models))))) OR (ethnographic view)) online, volume 1.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ethnographic videos) or (((ethnographic codes) OR (ethnographic models))))) or (ethnographic view)) online, volume 1".
• Adding a wildcard symbol may retrieve word variants: ((((ethnographic videos) or (((ethnographic codes) OR (ethnographic models))))) or (ethnographic view)) online, volume 1*.
