Perhaps you should try some spelling variations:
"element tracking algorithm" » "element learning algorithm" (Expand Search), "element processing algorithm" (Expand Search), "movement tracking algorithm" (Expand Search), "sleep tracking algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"client means algorithm" » "client search algorithm" (Expand Search), "client needs algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element each algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data algorithm" (Expand Search), "present data 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 tracking algorithm") OR ("element data algorithm"))) OR ("client means algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element tracking algorithm\") OR (\"element data algorithm\"))) OR (\"client means algorithm\"))".
• Removing quotes may allow a broader search: (((( element tracking algorithm ) OR ( element data algorithm ))) OR ( client means algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element tracking algorithm") OR ("element data algorithm"))) OR ("client means algorithm"))*.
