Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"relevant data algorithm" » "relevant jaya algorithm" (Expand Search), "relevant deer algorithm" (Expand Search)
"data backing algorithm" » "data banking algorithm" (Expand Search), "data lacking algorithm" (Expand Search), "data packing 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 algorithm") OR ((("data processing algorithm") OR ("data backing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithm\") OR (((\"data processing algorithm\") OR (\"data backing algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithm ) OR ((( data processing algorithm ) OR ( data backing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithm") OR ((("data processing algorithm") OR ("data backing algorithm"))))*.
