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 algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 ("element method algorithm"))) OR ("data backing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element method algorithm\"))) OR (\"data backing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element method algorithm ))) OR ( data backing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element method algorithm"))) OR ("data backing algorithm"))*.
