Perhaps you should try some spelling variations:
"fisheries management control." » "resources management control."
"city management activity." » "city management activities.", "city management facility.", "city management authority.", "data management activity.", "crop management activity.", "security management activity."
"case management quality." » "case management capacity.", "waste management quality.", "asset management quality.", "chain management quality."
"change management contracts." » "chain management contracts.", "finance management contracts.", "waste management contracts."
"demand management case." » "land management case.", "demand management a."
"cash management water." » "cash management data.", "cash management based.", "cash management a.", "asset management water."
"debt management case." » "debt management a."
"fire management concepts." » "side management concepts.", "zone management concepts.", "finance management concepts."

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: (((((((((("case management quality.") OR ("city management activity."))) OR ("fisheries management control."))) OR ("fire management concepts."))) OR ((((("demand management case.") OR ("debt management case."))) OR ("cash management water."))))) OR ("change management contracts."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((((\"case management quality.\") or (\"city management activity.\"))) or (\"fisheries management control.\"))) or (\"fire management concepts.\"))) or (((((\"demand management case.\") OR (\"debt management case.\"))) or (\"cash management water.\"))))) or (\"change management contracts.\"))~".
• Removing quotes may allow a broader search: (((((((((( case management quality. ) or ( city management activity. ))) or ( fisheries management control. ))) or ( fire management concepts. ))) or ((((( demand management case. ) OR ( debt management case. ))) or ( cash management water. ))))) or ( change management contracts. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((((((("case management quality.") or ("city management activity."))) or ("fisheries management control."))) or ("fire management concepts."))) or ((((("demand management case.") OR ("debt management case."))) or ("cash management water."))))) or ("change management contracts."))*.
