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)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element ii algorithm" » "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithm" (Expand Search), "element te 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 ((("element ii algorithm") OR ("element based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element matching algorithm\") OR (((\"element ii algorithm\") OR (\"element based algorithms\"))))".
• Removing quotes may allow a broader search: (( element matching algorithm ) OR ((( element ii algorithm ) OR ( element based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element matching algorithm") OR ((("element ii algorithm") OR ("element based algorithms"))))*.
