Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"element deer algorithm" » "element search algorithm" (Expand Search), "elementi per algorithm" (Expand Search)
"data relating algorithm" » "data regulating algorithm" (Expand Search), "data relations algorithm" (Expand Search), "data relative 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 processing algorithm") OR ("data relating algorithm"))) OR ("element deer algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"data relating algorithm\"))) OR (\"element deer algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( data relating algorithm ))) OR ( element deer algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("data relating algorithm"))) OR ("element deer algorithm"))*.
