Perhaps you should try some spelling variations:
ethnographic models » ethnographic mode, ethnographic notes, ethnographic moment
ethnographic scales » ethnographic case, ethnographic gazes, ethnographic tale
ethnographic video » ethnographic videos, ethnographic view, ethnographic index
ethnographic codes » ethnographic notes, ethnographic mode, 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 video) OR (ethnographic codes))) OR (((ethnographic models) OR (ethnographic scales)))) online, volume 1.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ethnographic video) OR (ethnographic codes))) or (((ethnographic models) or (ethnographic scales)))) online, volume 1".
• Adding a wildcard symbol may retrieve word variants: ((((ethnographic video) OR (ethnographic codes))) or (((ethnographic models) or (ethnographic scales)))) online, volume 1*.
