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