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)
"fluent modeling algorithm" » "fluent making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "forest modeling algorithm" (Expand Search), "plant modeling algorithm" (Expand Search)
"elements fe algorithms" » "elements de algorithms" (Expand Search), "elements five algorithms" (Expand Search), "elements ml algorithms" (Expand Search), "elements _ algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements b 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: (("elements fe algorithms") OR ((("fluent modeling algorithm") OR ("query processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements fe algorithms\") OR (((\"fluent modeling algorithm\") OR (\"query processing algorithm\"))))".
• Removing quotes may allow a broader search: (( elements fe algorithms ) OR ((( fluent modeling algorithm ) OR ( query processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements fe algorithms") OR ((("fluent modeling algorithm") OR ("query processing algorithm"))))*.
