Perhaps you should try some spelling variations:
"query modeling algorithm" » "query scheduling algorithm" (Expand Search)
"element learner algorithm" » "element learning algorithms" (Expand Search), "element search algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements learner algorithm" (Expand Search)
"relevant data algorithms" » "relevant jaya 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: (("relevant data algorithms") OR ((("query modeling algorithm") OR ("element learner algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithms\") OR (((\"query modeling algorithm\") OR (\"element learner algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithms ) OR ((( query modeling algorithm ) OR ( element learner algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithms") OR ((("query modeling algorithm") OR ("element learner algorithm"))))*.
