Perhaps you should try some spelling variations:
"data mining algorithm" » "data cosine algorithm" (Expand Search)
"element deer algorithm" » "element search algorithm" (Expand Search), "elementi per algorithm" (Expand Search)
"table 1_developing algorithm" » "stable 1_developing algorithm" (Expand Search), "tables 1_developing algorithm" (Expand Search), "able 1_developing 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: (((("table 1_developing algorithm") OR ("data mining algorithm"))) OR ("element deer algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"table 1_developing algorithm\") OR (\"data mining algorithm\"))) OR (\"element deer algorithm\"))".
• Removing quotes may allow a broader search: (((( table 1_developing algorithm ) OR ( data mining algorithm ))) OR ( element deer algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("table 1_developing algorithm") OR ("data mining algorithm"))) OR ("element deer algorithm"))*.
