Perhaps you should try some spelling variations:
"spatial modeling algorithm" » "spatial making algorithm" (Expand Search)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both 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: (("relevant data algorithms") OR ((("data using algorithms") OR ("spatial modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithms\") OR (((\"data using algorithms\") OR (\"spatial modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithms ) OR ((( data using algorithms ) OR ( spatial modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithms") OR ((("data using algorithms") OR ("spatial modeling algorithm"))))*.
