Perhaps you should try some spelling variations:
"query processing algorithm" » "pre processing algorithm" (Expand Search)
"sediment from algorithm" » "sediment em algorithm" (Expand Search), "sediment pso algorithm" (Expand Search), "sediment svm algorithm" (Expand Search), "sediment flux algorithm" (Expand Search)
"sediment size algorithm" » "sediment cosine algorithm" (Expand Search), "sediment five algorithms" (Expand Search), "sediment nine algorithms" (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 ((("sediment from algorithm") OR ("sediment size algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"query processing algorithm\") OR (((\"sediment from algorithm\") OR (\"sediment size algorithm\"))))".
• Removing quotes may allow a broader search: (( query processing algorithm ) OR ((( sediment from algorithm ) OR ( sediment size algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("query processing algorithm") OR ((("sediment from algorithm") OR ("sediment size algorithm"))))*.
