Perhaps you should try some spelling variations:
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)
"query finding algorithm" » "key finding 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 mesh algorithm") OR ((("query finding algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mesh algorithm\") OR (((\"query finding algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( element mesh algorithm ) OR ((( query finding algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mesh algorithm") OR ((("query finding algorithm") OR ("element method algorithm"))))*.
