Perhaps you should try some spelling variations:
structure process » structural process (Expand search), structural processes (Expand search), structure property (Expand search)
phrase structure » phase structure (Expand search), frame structure (Expand search), age structure (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the phrase » the phase (Expand search), the phases (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 the phrase structure process ) OR ( decrease will decrease during decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the phrase structure process ) OR ( decrease will decrease during decrease ))*.
