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)
"elements magic algorithm" » "elements making algorithm" (Expand Search), "elements mogwo algorithm" (Expand Search), "elements fastica algorithm" (Expand Search), "elements mges algorithm" (Expand Search)
"elements b algorithm" » "elements _ algorithm" (Expand Search), "elements box algorithm" (Expand Search), "elements dbo algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element g 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 magic algorithm") OR ("elements b algorithm"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements magic algorithm\") OR (\"elements b algorithm\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements magic algorithm ) OR ( elements b algorithm ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements magic algorithm") OR ("elements b algorithm"))) OR ("query processing algorithm"))*.
