Perhaps you should try some spelling variations:
quality processes » quality properties (Expand search), quality practices (Expand search), family processes (Expand search)
database quality » data quality (Expand search), database query (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during database » using database (Expand search), sting database (Expand search), aging database (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)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not 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 during database quality processes ) OR ( decrease can decrease toc decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during database quality processes ) OR ( decrease can decrease toc decrease ))*.
