Talvez debería tentar con algunhas variantes ortográficas:
"group improvements" » "crop improvement" (Expandir procura), "shows improvements" (Expandir procura), "show improvements" (Expandir procura)
"program implement" » "program improvements" (Expandir procura)
"program implementedingingedinged" » "program improvementsedingingedinged" (Expandir procura)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("program implement") OR ((("group improvements") OR ("program implementedingingedinged"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program implement\") OR (((\"group improvements\") OR (\"program implementedingingedinged\"))))".
• Removing quotes may allow a broader search: (( program implement ) OR ((( group improvements ) OR ( program implementedingingedinged )))).
• Adding a wildcard symbol may retrieve word variants: (("program implement") OR ((("group improvements") OR ("program implementedingingedinged"))))*.
