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 cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom algorithm" (Expand Search)
"elements new algorithm" » "elements novel algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "elements mges 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: (("query processing algorithm") OR ((("elements new algorithm") OR ("element cscap algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"query processing algorithm\") OR (((\"elements new algorithm\") OR (\"element cscap algorithm\"))))".
• Removing quotes may allow a broader search: (( query processing algorithm ) OR ((( elements new algorithm ) OR ( element cscap algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("query processing algorithm") OR ((("elements new algorithm") OR ("element cscap algorithm"))))*.
