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 two algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te 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 method algorithm") OR ("element two algorithms"))) OR ("query routing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element two algorithms\"))) OR (\"query routing algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element two algorithms ))) OR ( query routing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element two algorithms"))) OR ("query routing algorithm"))*.
