Perhaps you should try some spelling variations:
"case matching algorithm" » "case making algorithm" (Expand Search), "case modeling algorithm" (Expand Search), "case mining algorithm" (Expand Search), "score matching algorithm" (Expand Search), "closely matching algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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: (("case matching algorithm") OR ((("element cscap algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"case matching algorithm\") OR (((\"element cscap algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( case matching algorithm ) OR ((( element cscap algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("case matching algorithm") OR ((("element cscap algorithm") OR ("element method algorithm"))))*.
