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 means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element ore algorithms" » "element tree algorithms" (Expand Search), "element art algorithms" (Expand Search), "element rl algorithms" (Expand Search), "element te algorithms" (Expand Search), "element fbe algorithms" (Expand Search), "element ree algorithms" (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: (((("element ore algorithms") OR ("element method algorithm"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ore algorithms\") OR (\"element method algorithm\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element ore algorithms ) OR ( element method algorithm ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ore algorithms") OR ("element method algorithm"))) OR ("query processing algorithm"))*.
