"farm management control." » "farm management contracts.", "cash management control.", "bank management control.", "data management control."
"reform management control." » "reform management contracts.", "firm management control."
"land management data." » "land management case."
"land management a." » "land management _."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("land management data.") OR ("land management a."))) or ((("farm management control.") or ("reform management control."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("land management data.") OR ("land management a."))) OR ((("farm management control.") OR ("reform management control.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"land management data.\") OR (\"land management a.\"))) or (((\"farm management control.\") or (\"reform management control.\"))))".
• Removing quotes may allow a broader search: (((( land management data. ) OR ( land management a. ))) or ((( farm management control. ) or ( reform management control. )))).
• Adding a wildcard symbol may retrieve word variants: (((("land management data.") OR ("land management a."))) or ((("farm management control.") or ("reform management control."))))*.
