Perhaps you should try some spelling variations:
"elements matching algorithm" » "elements mining algorithm" (Expand Search), "elements sampling algorithm" (Expand Search), "elements tracking algorithm" (Expand Search), "elements within algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"china needs algorithm" » "china means algorithm" (Expand Search), "china new algorithm" (Expand Search), "china leiden algorithm" (Expand Search)
"client search algorithm" » "line search algorithm" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("client search algorithm") OR ("china needs algorithm"))) OR ("elements matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client search algorithm\") OR (\"china needs algorithm\"))) OR (\"elements matching algorithm\"))*".
• Removing quotes may allow a broader search: (((( client search algorithm ) OR ( china needs algorithm ))) OR ( elements matching algorithm ))*.
