Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search), "implemented routine algorithm" (Expand Search), "implementing routine algorithm" (Expand Search)
"element two algorithms" » "element _ algorithms" (Expand Search), "elements two algorithms" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements 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: (("implement routine algorithm") OR ((("element two algorithms") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement routine algorithm\") OR (((\"element two algorithms\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( implement routine algorithm ) OR ((( element two algorithms ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement routine algorithm") OR ((("element two algorithms") OR ("element mesh algorithm"))))*.
