Perhaps you should try some spelling variations:
"query routing algorithm" » "query modeling algorithm" (Expand Search), "query finding algorithm" (Expand Search), "query making algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element new algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements res algorithm" (Expand Search), "element te 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 routing algorithm") OR ((("element ree algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"query routing algorithm\") OR (((\"element ree algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( query routing algorithm ) OR ((( element ree algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("query routing algorithm") OR ((("element ree algorithm") OR ("element method algorithm"))))*.
