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)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (Expand Search)
"element based algorithm" » "engagement based 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: (("element matching algorithm") OR ((("elements tree algorithms") OR ("element based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element matching algorithm\") OR (((\"elements tree algorithms\") OR (\"element based algorithm\"))))".
• Removing quotes may allow a broader search: (( element matching algorithm ) OR ((( elements tree algorithms ) OR ( element based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element matching algorithm") OR ((("elements tree algorithms") OR ("element based algorithm"))))*.
