Perhaps you should try some spelling variations:
структур » структури (Expand Search), структуры (Expand Search), структура (Expand Search)
структураы » структуриаы (Expand Search), структурыаы (Expand Search), структурааы (Expand Search), структуры (Expand Search), структура (Expand Search), структурам (Expand Search)
структураи » структуриаи (Expand Search), структурыаи (Expand Search), структурааи (Expand Search), структури (Expand Search), структура (Expand Search), структурам (Expand Search)
структураиы » структуриаиы (Expand Search), структурыаиы (Expand Search), структурааиы (Expand Search), структуриы (Expand Search), структураы (Expand Search), структурамы (Expand Search), структури (Expand Search), структуры (Expand Search), структура (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( структур схема ) OR ( ((структураы OR структураи) OR структураиы) схема ))~".
• Adding a wildcard symbol may retrieve word variants: (( структур схема ) OR ( ((структураы OR структураи) OR структураиы) схема ))*.
