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)
"element method algorithms" » "element two algorithms" (Expand Search), "element other algorithms" (Expand Search), "element tested algorithms" (Expand Search)
"element em algorithm" » "element new algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element te algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element matching algorithm\") OR (((\"element method algorithms\") OR (\"element em algorithm\"))))~".
• Removing quotes may allow a broader search: (( element matching algorithm ) OR ((( element method algorithms ) OR ( element em algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element matching algorithm") OR ((("element method algorithms") OR ("element em algorithm"))))*.
