Perhaps you should try some spelling variations:
working patterns » foraging patterns (Expand search), working papers (Expand search), voting patterns (Expand search)
decrease working » decrease walking (Expand search), disease working (Expand search), decrease during (Expand search)
decrease burden » disease burden (Expand search), decrease further (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrees that » devices that (Expand search), trees that (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease burden decrees that decrease ) OR ( decrease can decrease working patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease burden decrees that decrease ) OR ( decrease can decrease working patterns ))*.
