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