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)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"recent study algorithm" » "recent wsindy algorithm" (Expand Search), "recent td3 algorithm" (Expand Search), "recent seu algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent studies 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 algorithms") OR ("recent study algorithm"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithms\") OR (\"recent study algorithm\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithms ) OR ( recent study algorithm ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithms") OR ("recent study algorithm"))) OR ("element matching algorithm"))*.
