Perhaps you should try some spelling variations:
accountability series » accountability crises, accountability berlin's, accountability security
accountability scales » accountability cases, accountability saber, accountability status
sector governance » water governance, der governance
public der » public de, public order, public under
public des » public de, public debts, public debt

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: "((\"public sector governance AND accountability series\") or (((\"((public der) OR (public des)) governance AND accountability series\") or (\"((public der) OR (public des)) governance AND accountability scales\"))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"public sector governance and accountability series\\") or (((\\"((public der) OR (public des)) governance and accountability series\\") or (\\"((public der) OR (public des)) governance and accountability scales\\"))))\"".
• Removing quotes may allow a broader search: (( public sector governance and accountability series ) or ((( ((public der) OR (public des)) governance and accountability series ) or ( ((public der) OR (public des)) governance and accountability scales )))).
