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)
"presence data algorithm" » "presence data algorithms" (Expand Search), "presence update algorithm" (Expand Search), "presence atlas algorithm" (Expand Search), "prevalence 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: (("presence data algorithm") OR ((("query processing algorithm") OR ("element meshs algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"presence data algorithm\") OR (((\"query processing algorithm\") OR (\"element meshs algorithm\"))))".
• Removing quotes may allow a broader search: (( presence data algorithm ) OR ((( query processing algorithm ) OR ( element meshs algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("presence data algorithm") OR ((("query processing algorithm") OR ("element meshs algorithm"))))*.
