Perhaps you should try some spelling variations:
"land management readers." » "land management centers.", "land management reform.", "land management reports."
"land management reviews." » "land management review.", "land management overview.", "land management reports."
"oxford management control." » "oxford management contracts.", "records management control.", "fund management control.", "flood management control."
"reform management control." » "reform management contracts.", "farm management control.", "firm 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: (((("land management readers.") or ("land management reviews."))) or ((("oxford management control.") OR ("reform management control."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("land management readers.") OR ("land management reviews."))) OR ((("oxford management control.") OR ("reform management control."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"land management readers.\") or (\"land management reviews.\"))) or (((\"oxford management control.\") OR (\"reform management control.\"))))*".
• Removing quotes may allow a broader search: (((( land management readers. ) or ( land management reviews. ))) or ((( oxford management control. ) OR ( reform management control. ))))*.
