• If you are trying to use Boolean operators, they must be ALL CAPS: (((("educaciones pedagogias") OR ("mediaciones pedagogicas"))) OR ((("mediacion tecnologica") OR ("educacion tecnologica"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"educaciones pedagogias\") OR (\"mediaciones pedagogicas\"))) or (((\"mediacion tecnologica\") or (\"educacion tecnologica\"))))*".
• Removing quotes may allow a broader search: (((( educaciones pedagogias ) OR ( mediaciones pedagogicas ))) or ((( mediacion tecnologica ) or ( educacion tecnologica ))))*.
