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 method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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 method algorithms") OR ("element rf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element matching algorithm\") OR (((\"element method algorithms\") OR (\"element rf algorithm\"))))".
• Removing quotes may allow a broader search: (( element matching algorithm ) OR ((( element method algorithms ) OR ( element rf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element matching algorithm") OR ((("element method algorithms") OR ("element rf algorithm"))))*.
