Perhaps you should try some spelling variations:
"demand management water." » "debt management water.", "demand management case.", "demand management data.", "demand management based."
"reform management contracts." » "farm management contracts.", "firm management contracts."
"flood management quality." » "fund management quality."
"data management water." » "data management case.", "data management data.", "data management based.", "debt management water.", "cash management water.", "chain management water."
"bank management control." » "basin management control.", "risk management control.", "cash management control."

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 control.") or ((("flood management quality.") or ("land management capacity."))))) or ((("data management water.") OR ("demand management water."))))) or ("reform management contracts."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("bank management control.") OR ((("flood management quality.") OR ("land management capacity."))))) OR ((("data management water.") OR ("demand management water."))))) OR ("reform management contracts."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"bank management control.\") or (((\"flood management quality.\") or (\"land management capacity.\"))))) or (((\"data management water.\") OR (\"demand management water.\"))))) or (\"reform management contracts.\"))*".
• Removing quotes may allow a broader search: (((((( bank management control. ) or ((( flood management quality. ) or ( land management capacity. ))))) or ((( data management water. ) OR ( demand management water. ))))) or ( reform management contracts. ))*.
