Perhaps you should try some spelling variations:
decrease placing » decrease replacing (Expand search), disease placing (Expand search), decreases weaning (Expand search)
placing objects » teaching objects (Expand search), speaking objects (Expand search), flying objects (Expand search)
increase food » increase blood (Expand search), increase bond (Expand search), increases blood (Expand search)
food decrease » food decreases (Expand search), foods decreases (Expand search), flow decrease (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on increase » on increased (Expand search), an increase (Expand search), in increase (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 on increase food decrease ) OR ( decrease AND decrease placing objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease on increase food decrease ) OR ( decrease AND decrease placing objects ))*.
