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)
"elements cnn algorithm" » "elements mean algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements ices algorithm" (Expand Search), "elements upon algorithm" (Expand Search)

Try widening your search to All Fields.

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

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