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)
"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)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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: (((("client needs algorithm") OR ("client learner algorithm"))) OR ("element means algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client needs algorithm\") OR (\"client learner algorithm\"))) OR (\"element means algorithm\"))".
• Removing quotes may allow a broader search: (((( client needs algorithm ) OR ( client learner algorithm ))) OR ( element means algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client needs algorithm") OR ("client learner algorithm"))) OR ("element means algorithm"))*.
