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)
"element method algorithm" » "element network algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element modbo algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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: (("query modeling algorithm") OR ((("element means algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"query modeling algorithm\") OR (((\"element means algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( query modeling algorithm ) OR ((( element means algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("query modeling algorithm") OR ((("element means algorithm") OR ("element method algorithm"))))*.
