Perhaps you should try some spelling variations:
"element content algorithm" » "element consistent algorithm" (Expand Search), "element control algorithm" (Expand Search), "element monte algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 algorithms") OR ((("element content algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data using algorithms\") OR (((\"element content algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( data using algorithms ) OR ((( element content algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data using algorithms") OR ((("element content algorithm") OR ("element method algorithm"))))*.
