Perhaps you should try some spelling variations:
"spatial sorting algorithms" » "spatial routing algorithm" (Expand Search), "spatial learning algorithms" (Expand Search), "spatial smoothing algorithms" (Expand Search), "spatial prompting algorithms" (Expand Search), "spatial modeling algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant 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: (((("relevant data algorithm") OR ("element method algorithm"))) OR ("spatial sorting algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element method algorithm\"))) OR (\"spatial sorting algorithms\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element method algorithm ))) OR ( spatial sorting algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element method algorithm"))) OR ("spatial sorting algorithms"))*.
