Perhaps you should try some spelling variations:
"client learner algorithm" » "client learning algorithm" (Expand Search), "client learning algorithms" (Expand Search), "client search algorithm" (Expand Search), "client server algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"client needs algorithm" » "client new algorithm" (Expand Search), "client leiden algorithm" (Expand Search), "client fedsam algorithm" (Expand Search), "urgent needs algorithm" (Expand Search), "china needs 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 means algorithm") OR ((("client needs algorithm") OR ("client learner algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element means algorithm\") OR (((\"client needs algorithm\") OR (\"client learner algorithm\"))))".
• Removing quotes may allow a broader search: (( element means algorithm ) OR ((( client needs algorithm ) OR ( client learner algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element means algorithm") OR ((("client needs algorithm") OR ("client learner algorithm"))))*.
