Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"case making algorithm" » "case learning algorithm" (Expand Search), "case finding algorithm" (Expand Search), "case means algorithm" (Expand Search), "cases taking algorithm" (Expand Search), "cheese making algorithm" (Expand Search), "case matching algorithm" (Expand Search)
"data modeling algorithm" » "data modelling algorithm" (Expand Search), "data models 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: (("elements method algorithm") OR ((("data modeling algorithm") OR ("case making algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data modeling algorithm\") OR (\"case making algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data modeling algorithm ) OR ( case making algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data modeling algorithm") OR ("case making algorithm"))))*.
