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