Perhaps you should try some spelling variations:
"element boosting algorithm" » "element cosine algorithm" (Expand Search), "elements boosting algorithm" (Expand Search)
"element mining algorithm" » "element cosine algorithm" (Expand Search), "elements mining algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "elements means 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 mining algorithm") OR ("element means algorithm"))) OR ("element boosting algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mining algorithm\") OR (\"element means algorithm\"))) OR (\"element boosting algorithm\"))".
• Removing quotes may allow a broader search: (((( element mining algorithm ) OR ( element means algorithm ))) OR ( element boosting algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mining algorithm") OR ("element means algorithm"))) OR ("element boosting algorithm"))*.
