Perhaps you should try some spelling variations:
"query processing algorithm" » "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "query boosting algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"key modeling algorithm" » "key making algorithm" (Expand Search), "fem modeling algorithm" (Expand Search), "decay modeling algorithm" (Expand Search), "best modeling algorithm" (Expand Search)
"sediment from algorithm" » "sediment frog algorithms" (Expand Search), "sediment pso algorithm" (Expand Search), "sediment rf algorithm" (Expand Search), "sediment flux 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 ("key modeling algorithm"))) OR ("sediment from algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"query processing algorithm\") OR (\"key modeling algorithm\"))) OR (\"sediment from algorithm\"))".
• Removing quotes may allow a broader search: (((( query processing algorithm ) OR ( key modeling algorithm ))) OR ( sediment from algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("query processing algorithm") OR ("key modeling algorithm"))) OR ("sediment from algorithm"))*.
