Perhaps you should try some spelling variations:
"query modeling algorithm" » "query making algorithm" (Expand Search), "energy modeling algorithm" (Expand Search), "key modeling algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data 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: (((("present data algorithm") OR ("relevant data algorithm"))) OR ("query modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present data algorithm\") OR (\"relevant data algorithm\"))) OR (\"query modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( present data algorithm ) OR ( relevant data algorithm ))) OR ( query modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present data algorithm") OR ("relevant data algorithm"))) OR ("query modeling algorithm"))*.
