Perhaps you should try some spelling variations:
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
decrease their » increase their (Expand search), decreases the (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
decrease toc » decrease of (Expand search), decreased to (Expand search), decrease on (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the comments » the comment (Expand search), the contents (Expand search), the components (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 will decrease toc decrease ) OR ( decrease their decrease the comments ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease will decrease toc decrease ) OR ( decrease their decrease the comments ))*.
