Perhaps you should try some spelling variations:
"design based using tools" » "device based using tools", "fusion based using tools", "design based nursing tools", "design gases using tools", "design based testing tools"
"functions based using tools" » "functions based nursing tools", "functions gases using tools", "functions based testing tools", "function based using tools"
"deim based using tools" » "deim based nursing tools", "deim gases using tools", "deim based testing tools", "device based using tools"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("functions based using tools") OR ((("design based using tools") OR ("deim based using tools"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"functions based using tools\") OR (((\"design based using tools\") OR (\"deim based using tools\"))))".
• Removing quotes may allow a broader search: (( functions based using tools ) OR ((( design based using tools ) OR ( deim based using tools )))).
• Adding a wildcard symbol may retrieve word variants: (("functions based using tools") OR ((("design based using tools") OR ("deim based using tools"))))*.
