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