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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"effect using algorithms" » "effect pacing algorithms" (Expand Search), "effect nine algorithms" (Expand Search), "effect sorting algorithms" (Expand Search), "effects using algorithms" (Expand Search), "effect size algorithms" (Expand Search)

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