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)
"data backing algorithm" » "data tracking algorithm" (Expand Search), "data making algorithm" (Expand Search), "data tracking algorithms" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method 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 method algorithm") OR ((("data modeling algorithm") OR ("data backing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data modeling algorithm\") OR (\"data backing algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data modeling algorithm ) OR ( data backing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data modeling algorithm") OR ("data backing algorithm"))))*.
