Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"settlement data algorithms" » "settlement art algorithms" (Expand Search), "settlement all algorithms" (Expand Search), "settlement both algorithms" (Expand Search)
"element study algorithm" » "element wsindy algorithm" (Expand Search), "element td3 algorithm" (Expand Search), "element seu algorithm" (Expand Search), "relevant study algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent study 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: (("data modeling algorithm") OR ((("settlement data algorithms") OR ("element study algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"settlement data algorithms\") OR (\"element study algorithm\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( settlement data algorithms ) OR ( element study algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("settlement data algorithms") OR ("element study algorithm"))))*.
