Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"element meshs algorithm" » "element means algorithm" (Expand Search), "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "element method algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent 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: (("present data algorithm") OR ((("query processing algorithm") OR ("element meshs algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present data algorithm\") OR (((\"query processing algorithm\") OR (\"element meshs algorithm\"))))".
• Removing quotes may allow a broader search: (( present data algorithm ) OR ((( query processing algorithm ) OR ( element meshs algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present data algorithm") OR ((("query processing algorithm") OR ("element meshs algorithm"))))*.
