"materia nutrition" » "materia nutritiva", "materia nutritivo"
"maternal nutricion" » "internal nutricion", "external nutricion"

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"material nutrition\") OR (\"materia nutrition\"))) OR (((((\"maternal nutricion\") OR (\"materials nutricion\"))) OR (\"materna nutricion\"))))) OR (((\"material nutrition\") OR (\"materia nutrition\"))))".
• Removing quotes may allow a broader search: (((((( material nutrition ) OR ( materia nutrition ))) OR ((((( maternal nutricion ) OR ( materials nutricion ))) OR ( materna nutricion ))))) OR ((( material nutrition ) OR ( materia nutrition )))).
• Adding a wildcard symbol may retrieve word variants: (((((("material nutrition") OR ("materia nutrition"))) OR ((((("maternal nutricion") OR ("materials nutricion"))) OR ("materna nutricion"))))) OR ((("material nutrition") OR ("materia nutrition"))))*.
