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)
"case matching algorithm" » "case making algorithm" (Expand Search), "case mining algorithm" (Expand Search), "case tracking algorithm" (Expand Search), "score matching algorithm" (Expand Search), "closely matching algorithm" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method 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 matching algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data modeling algorithm\") OR (\"case matching algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data modeling algorithm ) OR ( case matching algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data modeling algorithm") OR ("case matching algorithm"))))*.
