Perhaps you should try some spelling variations:
"level using algorithm" » "level cosine algorithm" (Expand Search), "level fusion algorithm" (Expand Search)
"elements deer algorithm" » "elements search algorithm" (Expand Search), "elementi per algorithm" (Expand Search)
"implement finding algorithm" » "implemented finding algorithm" (Expand Search), "implementing finding algorithm" (Expand Search), "implement findings 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: (("implement finding algorithm") OR ((("elements deer algorithm") OR ("level using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement finding algorithm\") OR (((\"elements deer algorithm\") OR (\"level using algorithm\"))))".
• Removing quotes may allow a broader search: (( implement finding algorithm ) OR ((( elements deer algorithm ) OR ( level using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement finding algorithm") OR ((("elements deer algorithm") OR ("level using algorithm"))))*.
