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