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