Perhaps you should try some spelling variations:
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"elements making algorithm" » "elements learning algorithm" (Expand Search), "elements finding algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements during algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search)
"data modeling algorithm" » "data modelling algorithm" (Expand Search), "data models 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 using algorithms") OR ("data modeling algorithm"))) OR ("elements making algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithms\") OR (\"data modeling algorithm\"))) OR (\"elements making algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithms ) OR ( data modeling algorithm ))) OR ( elements making algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithms") OR ("data modeling algorithm"))) OR ("elements making algorithm"))*.
