Perhaps you should try some spelling variations:
"cash management controls." » "cash management contract.", "cash management tools.", "cash management functions.", "asset management controls."
"land management quality." » "land management capacity."
"finance management concepts." » "financial management concepts."
"land management water." » "land management data.", "land management based.", "land management a."
"debt management board." » "debt management a.", "debt management data.", "debt management how."
"care management contracts." » "case management contracts.", "fire management contracts.", "change management contracts."
"land management case." » "land management a."

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: (((((("waste management control.") OR ((("care management contracts.") OR ("cash management controls."))))) OR ((((((("land management water.") OR ("land management case."))) OR ("land management quality."))) OR ("debt management board."))))) OR ("finance management concepts."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"waste management control.\") or (((\"care management contracts.\") or (\"cash management controls.\"))))) or (((((((\"land management water.\") OR (\"land management case.\"))) or (\"land management quality.\"))) or (\"debt management board.\"))))) or (\"finance management concepts.\"))~".
• Removing quotes may allow a broader search: (((((( waste management control. ) or ((( care management contracts. ) or ( cash management controls. ))))) or ((((((( land management water. ) OR ( land management case. ))) or ( land management quality. ))) or ( debt management board. ))))) or ( finance management concepts. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("waste management control.") or ((("care management contracts.") or ("cash management controls."))))) or ((((((("land management water.") OR ("land management case."))) or ("land management quality."))) or ("debt management board."))))) or ("finance management concepts."))*.
