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 means algorithm" » "elements search algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "elements res algorithm" (Expand Search)
"data code algorithm" » "data cosine algorithm" (Expand Search), "data novel algorithm" (Expand Search), "data modbo algorithm" (Expand Search), "data model algorithm" (Expand Search), "data came 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 means algorithm") OR ((("data code algorithm") OR ("data modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements means algorithm\") OR (((\"data code algorithm\") OR (\"data modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements means algorithm ) OR ((( data code algorithm ) OR ( data modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements means algorithm") OR ((("data code algorithm") OR ("data modeling algorithm"))))*.
