Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element modbo algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("query processing algorithm") OR ("element means algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"query processing algorithm\") OR (\"element means algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( query processing algorithm ) OR ( element means algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("query processing algorithm") OR ("element means algorithm"))) OR ("element method algorithm"))*.
