Perhaps you should try some spelling variations:
"learning-based code floatation technique" » "learning-based code inhalation technique", "learning-based code implantation technique", "learning-based code imputation techniques", "learning-based anode floatation technique"
"learning-based two inhaler technique" » "learning-based two inhalation technique", "learning-based tool inhaler technique", "learning-based co inhaler technique"

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: "((\"learning-based two inhaler technique\") OR (\"learning-based code floatation technique\"))~".
• Removing quotes may allow a broader search: (( learning-based two inhaler technique ) OR ( learning-based code floatation technique ))~.
• Adding a wildcard symbol may retrieve word variants: (("learning-based two inhaler technique") OR ("learning-based code floatation technique"))*.
