Perhaps you should try some spelling variations:
"based matching algorithms" » "based matching algorithm" (Expand Search), "based pacing algorithms" (Expand Search), "based making algorithm" (Expand Search), "based machine algorithms" (Expand Search), "case matching algorithms" (Expand Search), "based teaching algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("data using algorithm") OR ("based matching algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"based matching algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( based matching algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("based matching algorithms"))) OR ("element method algorithm"))*.
