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