Perhaps you should try some spelling variations:
"element matching algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data algorithm" (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: (((("present data algorithm") OR ("element data algorithm"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present data algorithm\") OR (\"element data algorithm\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( present data algorithm ) OR ( element data algorithm ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present data algorithm") OR ("element data algorithm"))) OR ("element matching algorithm"))*.
