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