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