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