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 mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element fbe algorithm" » "element b algorithm" (Expand Search), "element dbo algorithm" (Expand Search), "element abs algorithm" (Expand Search), "element te algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "element ore 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 mapping algorithm"))) OR ("element fbe algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"query processing algorithm\") OR (\"element mapping algorithm\"))) OR (\"element fbe algorithm\"))".
• Removing quotes may allow a broader search: (((( query processing algorithm ) OR ( element mapping algorithm ))) OR ( element fbe algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("query processing algorithm") OR ("element mapping algorithm"))) OR ("element fbe algorithm"))*.
