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