Perhaps you should try some spelling variations:
"query processing algorithm" » "query modeling algorithm" (Expand Search), "query routing algorithm" (Expand Search), "query tracking algorithm" (Expand Search), "pre processing algorithm" (Expand Search)
"element mesh algorithms" » "element best algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element best algorithm" (Expand Search), "element method algorithms" (Expand Search), "elements mges algorithms" (Expand Search), "element te algorithms" (Expand Search)
"element each algorithm" » "element search algorithm" (Expand Search), "element means algorithm" (Expand Search), "element data 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: (((("element each algorithm") OR ("element mesh algorithms"))) OR ("query processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element each algorithm\") OR (\"element mesh algorithms\"))) OR (\"query processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element each algorithm ) OR ( element mesh algorithms ))) OR ( query processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element each algorithm") OR ("element mesh algorithms"))) OR ("query processing algorithm"))*.
