Perhaps you should try some spelling variations:
"learning-based closed reduction techniques" » "learning-based closed reduction technique", "learning-based closed imputation techniques", "learning-based model reduction techniques", "learning-based code reduction techniques", "learning-based cross reduction techniques"
"learning-based anodes indication technique" » "learning-based anodes inhalation technique", "learning-based anodes reduction technique", "learning-based anodes truncation technique", "learning-based novel indication technique", "learning-based anode indication technique", "learning-based code indication technique"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("learning-based anodes indication technique") or ("learning-based closed reduction techniques"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("learning-based anodes indication technique") OR ("learning-based closed reduction techniques"))*.
• Removing quotes may allow a broader search: (( learning-based anodes indication technique ) or ( learning-based closed reduction techniques ))*.
