Perhaps you should try some spelling variations:
oncologica relacional » psicologica relacionada, logico relacional
sociologia relacional » tecnologia relacionada, psicologia relacion, sociologia laboral
ontologia relacional » autonomia relacional, teoria relacional
oncologia nacional » economia nacional, logia nacional
oncologico » ecologico, deontologico

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( instituto ((oncologia nacional) or (oncologico nacional)) ) or ( institucion ((oncologica relacional) or (((sociologia relacional) OR (ontologia relacional)))) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( instituto ((oncologia nacional) OR (oncologico nacional)) ) OR ( institucion ((oncologica relacional) OR (((sociologia relacional) OR (ontologia relacional)))) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( instituto ((oncologia nacional) or (oncologico nacional)) ) or ( institucion ((oncologica relacional) or (((sociologia relacional) OR (ontologia relacional)))) ))".
• Adding a wildcard symbol may retrieve word variants: (( instituto ((oncologia nacional) or (oncologico nacional)) ) or ( institucion ((oncologica relacional) or (((sociologia relacional) OR (ontologia relacional)))) ))*.
