Perhaps you should try some spelling variations:
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data algorithm" (Expand Search)
"spatial search algorithm" » "optimal search algorithm" (Expand Search), "spatial hierarchy 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 data algorithm") OR ("element method algorithms"))) OR ("spatial search algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element data algorithm\") OR (\"element method algorithms\"))) OR (\"spatial search algorithm\"))".
• Removing quotes may allow a broader search: (((( element data algorithm ) OR ( element method algorithms ))) OR ( spatial search algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element data algorithm") OR ("element method algorithms"))) OR ("spatial search algorithm"))*.
