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