Perhaps you should try some spelling variations:
"land management authority." » "land management quality.", "land management _uthority."
"land management _uthority." » "land management authorities.", "land management quality.", "land management activity."
"land management entity." » "land management energy.", "land management activity.", "land management quality."
"reform management tools." » "firm management tools."
"bank management contracts." » "basin management contracts.", "risk management contracts.", "demand management contracts."
"cash management data." » "asset management data.", "cash management case."
"farm management control." » "data management control.", "forest management control.", "basin management control."
"debt management a." » "debt management _."

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 contracts.") or ((("land management entity.") or ((("land management authority.") or ("land management _uthority."))))))) or ((("cash management data.") or ("debt management a."))))) or ((("reform management tools.") or ((("farm management control.") OR ("chain management control."))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("bank management contracts.") OR ((("land management entity.") OR ((("land management authority.") OR ("land management _uthority."))))))) OR ((("cash management data.") OR ("debt management a."))))) OR ((("reform management tools.") OR ((("farm management control.") OR ("chain management control."))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"bank management contracts.\") or (((\"land management entity.\") or (((\"land management authority.\") or (\"land management _uthority.\"))))))) or (((\"cash management data.\") or (\"debt management a.\"))))) or (((\"reform management tools.\") or (((\"farm management control.\") OR (\"chain management control.\"))))))*".
• Removing quotes may allow a broader search: (((((( bank management contracts. ) or ((( land management entity. ) or ((( land management authority. ) or ( land management _uthority. ))))))) or ((( cash management data. ) or ( debt management a. ))))) or ((( reform management tools. ) or ((( farm management control. ) OR ( chain management control. ))))))*.
