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)
"data using algorithms" » "data pacing algorithms" (Expand Search), "data nine algorithms" (Expand Search), "data sorting algorithms" (Expand Search)
"element te algorithm" » "element tide algorithm" (Expand Search), "element new algorithm" (Expand Search), "element de algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element g algorithm" (Expand Search), "element data 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 ("element te algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithms\") OR (\"data modeling algorithm\"))) OR (\"element te algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithms ) OR ( data modeling algorithm ))) OR ( element te algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithms") OR ("data modeling algorithm"))) OR ("element te algorithm"))*.
