Perhaps you should try some spelling variations:
"case management authority." » "case management quality.", "waste management authority.", "change management authority.", "asset management authority.", "case management _uthority."
"reform management contract." » "reform management contracts.", "reform management control.", "farm management contract.", "firm management contract."
"basin management controls." » "basin management control.", "basin management contracts.", "basin management tools.", "chain management controls.", "business management controls.", "crisis management controls."
"side management concepts." » "side management contracts.", "zone management concepts.", "service management concepts.", "border management concepts."
"budget management concepts." » "budget management contracts.", "debt management concepts.", "asset management concepts."
"cash management energy." » "cash management entity.", "cash management centers.", "cash management agency.", "asset management energy."
"flood management a." » "land management a.", "fund management a.", "flood management _."
"flood management case." » "land management case.", "fund management case."

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: (((((("basin management controls.") OR ((("flood management a.") OR ("flood management case."))))) OR ((((("cash management energy.") OR ("case management authority."))) OR ((("side management concepts.") OR ("budget management concepts."))))))) OR ("reform management contract."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"basin management controls.\") or (((\"flood management a.\") or (\"flood management case.\"))))) or (((((\"cash management energy.\") or (\"case management authority.\"))) or (((\"side management concepts.\") OR (\"budget management concepts.\"))))))) or (\"reform management contract.\"))~".
• Removing quotes may allow a broader search: (((((( basin management controls. ) or ((( flood management a. ) or ( flood management case. ))))) or ((((( cash management energy. ) or ( case management authority. ))) or ((( side management concepts. ) OR ( budget management concepts. ))))))) or ( reform management contract. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("basin management controls.") or ((("flood management a.") or ("flood management case."))))) or ((((("cash management energy.") or ("case management authority."))) or ((("side management concepts.") OR ("budget management concepts."))))))) or ("reform management contract."))*.
