Perhaps you should try some spelling variations:
"card sorting algorithms" » "card routing algorithm" (Expand Search), "card learning algorithms" (Expand Search), "cell sorting algorithms" (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: (("card sorting algorithms") OR ((("element cscap algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"card sorting algorithms\") OR (((\"element cscap algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( card sorting algorithms ) OR ((( element cscap algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("card sorting algorithms") OR ((("element cscap algorithm") OR ("element method algorithm"))))*.
