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