Perhaps you should try some spelling variations:
quality properties » stability properties (Expand search), qualitative properties (Expand search)
database quality » data quality (Expand search), database query (Expand search)
decrease taping » decrease walking (Expand search), decrease during (Expand search), decrease owing (Expand search)
taping decrease » training decreases (Expand search)
decrease of » decrease in (Expand search)
of database » _ database (Expand search), and database (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease of database quality properties ) OR ( decrease to decrease taping decrease ))~.
