Perhaps you should try some spelling variations:
ethnographic models » ethnographic mode, ethnographic moments, ethnographic notes
ethnographic index » ethnographic mode, ethnographic video, ethnographic issues
ethnographic codes » ethnographic notes, ethnographic mode, ethnographic scales

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