Perhaps you should try some spelling variations:
"query processing algorithm" » "pre processing algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant each algorithm" (Expand Search)
"elements ree algorithms" » "elements tree algorithms" (Expand Search), "elements three algorithms" (Expand Search), "elements rl algorithms" (Expand Search), "elements _ algorithms" (Expand Search), "elements present algorithms" (Expand Search), "elements related algorithms" (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 algorithm") OR ("elements ree algorithms"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"elements ree algorithms\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( elements ree algorithms ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("elements ree algorithms"))) OR ("query processing algorithm"))*.
