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)
"elements three algorithms" » "elements forest algorithms" (Expand Search), "elements based algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (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: (((("elements three algorithms") OR ("element method algorithm"))) OR ("data modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements three algorithms\") OR (\"element method algorithm\"))) OR (\"data modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements three algorithms ) OR ( element method algorithm ))) OR ( data modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements three algorithms") OR ("element method algorithm"))) OR ("data modeling algorithm"))*.
