Perhaps you should try some spelling variations:
основее\" » основе\" (Expand Search), основные\" (Expand Search), основіее\" (Expand Search), основеее\" (Expand Search)
основеі\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіеі\" (Expand Search), основееі\" (Expand Search)
основеііе\" » основііе\" (Expand Search), основеіе\" (Expand Search), основнііе\" (Expand Search), основіеііе\" (Expand Search), основееііе\" (Expand Search)
основені\" » основні\" (Expand Search), основі\" (Expand Search), основе\" (Expand Search), основіені\" (Expand Search), основеені\" (Expand Search)
основ\" » основі\" (Expand Search), основе\" (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: "\"((\\"ґрунтова ((основее\\" OR (основеі\\" OR основені\\")) OR основеііе\\")) OR (\\"ґрунтова основ\\"))~\"".
• Removing quotes may allow a broader search: (( ґрунтова ((основее OR (основеі OR основені )) OR основеііе )) OR ( ґрунтова основ ))~.
