• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("implicaciones pedagogicas") OR ("mediaciones pedagogicas"))) OR ("implicaciones practicas"))) OR ((("mediacion pedagogica") OR ("investigacion pedagogica")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"implicaciones pedagogicas\") or (\"mediaciones pedagogicas\"))) or (\"implicaciones practicas\"))) or (((\"mediacion pedagogica\") OR (\"investigacion pedagogica\"))))".
• Removing quotes may allow a broader search: (((((( implicaciones pedagogicas ) or ( mediaciones pedagogicas ))) or ( implicaciones practicas ))) or ((( mediacion pedagogica ) OR ( investigacion pedagogica )))).
• Adding a wildcard symbol may retrieve word variants: (((((("implicaciones pedagogicas") or ("mediaciones pedagogicas"))) or ("implicaciones practicas"))) or ((("mediacion pedagogica") OR ("investigacion pedagogica"))))*.
