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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements cnn algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cnn algorithm\") OR (\"relevant data algorithm\"))) OR (\"query processing algorithm\"))~".
• Removing quotes may allow a broader search: (((( element cnn algorithm ) OR ( relevant data algorithm ))) OR ( query processing algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element cnn algorithm") OR ("relevant data algorithm"))) OR ("query processing algorithm"))*.
