Perhaps you should try some spelling variations:
"reform management contractss." » "reform management contracts.", "reform management contractors.", "reform management contract.", "farm management contractss.", "firm management contractss."
"land management activity." » "land management activities.", "land management facility.", "land management authority.", "land management _ctivity."
"cash management control." » "cash management contracts.", "asset management control."
"waste management water." » "debt management water.", "waste management data.", "waste management based.", "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.

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