managing object » handling object (Expand search), managing projects (Expand search), mediating object (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)

the decrees » the decree (Expand search), the degrees (Expand search), the decrease (Expand search)
decrees not » decrees of (Expand search), decrees on (Expand search), decrees that (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease pro (Expand search)

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: (( decrease the decrees NOT decrease ) OR ( decrease to decrease managing object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the decrees not decrease ) OR ( decrease to decrease managing object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrees not decrease ) OR ( decrease to decrease managing object ))*.
