Perhaps you should try some spelling variations:
"query processing algorithm" » "query processing algorithms" (Expand Search), "text processing algorithm" (Expand Search)
"present data algorithms" » "present jaya algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

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