Perhaps you should try some spelling variations:
"element custom algorithm" » "element control algorithm" (Expand Search), "element auction algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements custom algorithm" (Expand Search)
"data using algorithm" » "data cosine algorithm" (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: (("data using algorithm") OR ((("element custom algorithm") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithm\") OR (((\"element custom algorithm\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( data using algorithm ) OR ((( element custom algorithm ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithm") OR ((("element custom algorithm") OR ("element mesh algorithm"))))*.
