Perhaps you should try some spelling variations:
"reform management contractss." » "reform management contracts.", "reform management contractors.", "reform management controls.", "reform management contractsss.", "farm management contractss.", "firm management contractss."
"land management activity." » "land management activities.", "land management facility.", "land management authority.", "land management _ctivity."
"reform management contract." » "reform management contracts.", "farm management contract.", "firm management contract."
"cash management control." » "cash management contracts.", "asset management control."
"land management quality." » "land management capacity."
"chain management based." » "chain management case.", "chain management board.", "chain management issues."
"waste management water." » "debt management water.", "waste management case.", "waste management data.", "waste management areas."
"case management a." » "change management a.", "asset management a.", "basin management a.", "case management _."

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("cash management control.") OR ((("land management quality.") OR ("land management activity."))))) OR ((((("chain management based.") OR ("waste management water."))) OR ("case management a."))))) OR ((("reform management contractss.") OR ("reform management contract."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"cash management control.\") or (((\"land management quality.\") or (\"land management activity.\"))))) or (((((\"chain management based.\") or (\"waste management water.\"))) or (\"case management a.\"))))) or (((\"reform management contractss.\") OR (\"reform management contract.\"))))~".
• Removing quotes may allow a broader search: (((((( cash management control. ) or ((( land management quality. ) or ( land management activity. ))))) or ((((( chain management based. ) or ( waste management water. ))) or ( case management a. ))))) or ((( reform management contractss. ) OR ( reform management contract. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((((("cash management control.") or ((("land management quality.") or ("land management activity."))))) or ((((("chain management based.") or ("waste management water."))) or ("case management a."))))) or ((("reform management contractss.") OR ("reform management contract."))))*.
