Perhaps you should try some spelling variations:
"land management _ctivities." » "land management activities.", "land management activity.", "land management facilities."
"land management facility." » "land management capacity.", "land management quality."
"reform management contract." » "farm management contract.", "firm management contract."
"asset management case." » "debt management case."
"waste management a." » "debt management a.", "waste management _."
"bank management control." » "basin management control.", "risk management control.", "demand management control."
"bank management contracts." » "basin management contracts.", "risk management contracts.", "demand management contracts."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((((((("bank management control.") OR ("bank management contracts."))) or ("cash management control."))) or ((("land management facility.") or ("land management _ctivities."))))) or ((("asset management case.") or ("waste management a."))))) or ("reform management contract."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((((("bank management control.") OR ("bank management contracts."))) OR ("cash management control."))) OR ((("land management facility.") OR ("land management _ctivities."))))) OR ((("asset management case.") OR ("waste management a."))))) OR ("reform management contract."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((((\"bank management control.\") OR (\"bank management contracts.\"))) or (\"cash management control.\"))) or (((\"land management facility.\") or (\"land management _ctivities.\"))))) or (((\"asset management case.\") or (\"waste management a.\"))))) or (\"reform management contract.\"))*".
• Removing quotes may allow a broader search: (((((((((( bank management control. ) OR ( bank management contracts. ))) or ( cash management control. ))) or ((( land management facility. ) or ( land management _ctivities. ))))) or ((( asset management case. ) or ( waste management a. ))))) or ( reform management contract. ))*.
