Perhaps you should try some spelling variations:
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease space » decrease age (Expand search), disease space (Expand search), decreases species (Expand search)
space objects » space projects (Expand search), image objects (Expand search), black objects (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt increase » gait increase (Expand search), ants increase (Expand search), and increase (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), or 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 akt increase during decrease ) OR ( decrease on decrease space objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt increase during decrease ) OR ( decrease on decrease space objects ))*.
