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 mapping algorithm" » "elements making algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "elements learning algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "elements during algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (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 algorithms") OR ("elements mapping algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"relevant data algorithms\") OR (\"elements mapping algorithm\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( relevant data algorithms ) OR ( elements mapping algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("relevant data algorithms") OR ("elements mapping algorithm"))))*.
