Talvez debería tentar con algunhas variantes ortográficas:
"group improvements" » "crop improvement" (Expandir procura), "shows improvements" (Expandir procura), "show improvements" (Expandir procura)
"program implementinginged" » "program implementingrules" (Expandir procura)
"program complement" » "program complementary" (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: (("group improvements") OR ((("program implementinginged") OR ("program complement"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"group improvements\") OR (((\"program implementinginged\") OR (\"program complement\"))))".
• Removing quotes may allow a broader search: (( group improvements ) OR ((( program implementinginged ) OR ( program complement )))).
• Adding a wildcard symbol may retrieve word variants: (("group improvements") OR ((("program implementinginged") OR ("program complement"))))*.
