• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"ґрунтова ((основіе\\" OR основіеніеные\\") OR основііеіеіеееееные\\")) OR (\\"ґрунтова основ\\"))~\"".
• Removing quotes may allow a broader search: (( ґрунтова ((основіе OR основіеніеные ) OR основііеіеіеееееные )) OR ( ґрунтова основ ))~.
