Perhaps you should try some spelling variations:
"complementary and alternative depictions" » "complementary and alternative designs" (Expand Search), "complementary and alternative option" (Expand Search), "complementary and alternative radiation" (Expand Search)
"complementary and alternative antigens" » "complementary and alternative designs" (Expand Search), "complementary and alternative nitrogen" (Expand Search), "complementary and alternative nutrient" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"complementary and alternative depictions\") OR (\"complementary and alternative antigens\"))~".
• Removing quotes may allow a broader search: (( complementary and alternative depictions ) OR ( complementary and alternative antigens ))~.
• Adding a wildcard symbol may retrieve word variants: (("complementary and alternative depictions") OR ("complementary and alternative antigens"))*.
