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)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res 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: (("data modeling algorithm") OR ((("elements tree algorithms") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"elements tree algorithms\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( elements tree algorithms ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("elements tree algorithms") OR ("element method algorithm"))))*.
