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 method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"cell clustering algorithm" » "cell clusters algorithm" (Expand Search), "means clustering 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 ("cell clustering algorithm"))) OR ("element method algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modeling algorithm\") OR (\"cell clustering algorithm\"))) OR (\"element method algorithms\"))".
• Removing quotes may allow a broader search: (((( data modeling algorithm ) OR ( cell clustering algorithm ))) OR ( element method algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data modeling algorithm") OR ("cell clustering algorithm"))) OR ("element method algorithms"))*.
