Perhaps you should try some spelling variations:
"query processing algorithm" » "query processing algorithms" (Expand Search), "text processing algorithm" (Expand Search)
"element cscap algorithm" » "element cosine algorithm" (Expand Search)
"element new algorithm" » "element deer algorithm" (Expand Search), "element rd algorithm" (Expand Search), "elementi per 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 processing algorithm") OR ((("element new algorithm") OR ("element cscap algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"query processing algorithm\") OR (((\"element new algorithm\") OR (\"element cscap algorithm\"))))".
• Removing quotes may allow a broader search: (( query processing algorithm ) OR ((( element new algorithm ) OR ( element cscap algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("query processing algorithm") OR ((("element new algorithm") OR ("element cscap algorithm"))))*.
