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 td3 algorithm" » "element cc3d algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element te algorithm" (Expand Search), "element study algorithm" (Expand Search)
"element svm algorithm" » "element em algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements ppm 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: (((("element td3 algorithm") OR ("element svm algorithm"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element td3 algorithm\") OR (\"element svm algorithm\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element td3 algorithm ) OR ( element svm algorithm ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element td3 algorithm") OR ("element svm algorithm"))) OR ("query processing algorithm"))*.
