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