Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"elements method algorithms" » "elements two algorithms" (Expand Search), "elements both algorithms" (Expand Search), "elements other algorithms" (Expand Search), "element method algorithms" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 algorithms") OR ("relevant data algorithm"))) OR ("data modelling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithms\") OR (\"relevant data algorithm\"))) OR (\"data modelling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithms ) OR ( relevant data algorithm ))) OR ( data modelling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithms") OR ("relevant data algorithm"))) OR ("data modelling algorithm"))*.
