Perhaps you should try some spelling variations:
"data backing algorithm" » "data tracking algorithm" (Expand Search), "data making algorithm" (Expand Search), "data tracking algorithms" (Expand Search)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (("data backing algorithm") OR ((("element method algorithms") OR ("element data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data backing algorithm\") OR (((\"element method algorithms\") OR (\"element data algorithm\"))))".
• Removing quotes may allow a broader search: (( data backing algorithm ) OR ((( element method algorithms ) OR ( element data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data backing algorithm") OR ((("element method algorithms") OR ("element data algorithm"))))*.
