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)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas 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: (((("elements method algorithm") OR ("settlement data algorithm"))) OR ("query routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"settlement data algorithm\"))) OR (\"query routing algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( settlement data algorithm ))) OR ( query routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("settlement data algorithm"))) OR ("query routing algorithm"))*.
