Perhaps you should try some spelling variations:
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"data clustering algorithm" » "deep clustering algorithm" (Expand Search), "spatial clustering algorithm" (Expand Search), "dbscan clustering algorithm" (Expand Search)
"spine using algorithm" » "spine using algorithms" (Expand Search), "spine routing algorithm" (Expand Search), "spine fusion algorithm" (Expand Search), "space using algorithm" (Expand Search), "site using algorithm" (Expand Search), "joined using algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("relevant data algorithms") OR ((("data clustering algorithm") OR ("spine using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithms\") OR (((\"data clustering algorithm\") OR (\"spine using algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithms ) OR ((( data clustering algorithm ) OR ( spine using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithms") OR ((("data clustering algorithm") OR ("spine using algorithm"))))*.
