• If you are trying to use Boolean operators, they must be ALL CAPS: (((("plant gender research.") OR ((("plant teacher research.") OR ("art teaching research."))))) OR ((((("plant zone research.") OR ("plant gene research."))) OR ("plant case research.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"plant gender research.\") or (((\"plant teacher research.\") or (\"art teaching research.\"))))) or (((((\"plant zone research.\") OR (\"plant gene research.\"))) or (\"plant case research.\"))))".
• Removing quotes may allow a broader search: (((( plant gender research. ) or ((( plant teacher research. ) or ( art teaching research. ))))) or ((((( plant zone research. ) OR ( plant gene research. ))) or ( plant case research. )))).
• Adding a wildcard symbol may retrieve word variants: (((("plant gender research.") or ((("plant teacher research.") or ("art teaching research."))))) or ((((("plant zone research.") OR ("plant gene research."))) or ("plant case research."))))*.
