Perhaps you should try some spelling variations:
"ethnographic video online, volume 1" » "ethnographic videos online, volume 1", "ethnographic view online, volume 1", "ethnographic codes online, volume 1", "ethnographic do online, volume 1"
"ethnographic data online, volume 1" » "ethnographic case online, volume 1", "oceanographic data online, volume 1"

Try widening your search to All Fields.

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 online, volume 1") OR ((("ethnographic data online, volume 1") OR ("ethnographic _ online, volume 1")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ethnographic video online, volume 1\") or (((\"ethnographic data online, volume 1\") OR (\"ethnographic _ online, volume 1\"))))".
• Removing quotes may allow a broader search: (( ethnographic video online, volume 1 ) or ((( ethnographic data online, volume 1 ) OR ( ethnographic _ online, volume 1 )))).
• Adding a wildcard symbol may retrieve word variants: (("ethnographic video online, volume 1") or ((("ethnographic data online, volume 1") OR ("ethnographic _ online, volume 1"))))*.
