Perhaps you should try some spelling variations:
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant de algorithms" (Expand Search)
"fold processing algorithm" » "food processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "post processing algorithm" (Expand Search)
"element em algorithm" » "element new algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element te 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: (((("relevant data algorithms") OR ("element em algorithm"))) OR ("fold processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithms\") OR (\"element em algorithm\"))) OR (\"fold processing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithms ) OR ( element em algorithm ))) OR ( fold processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithms") OR ("element em algorithm"))) OR ("fold processing algorithm"))*.
