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)
"post clustering algorithm" » "host clustering algorithm" (Expand Search), "novo clustering algorithm" (Expand Search), "som clustering algorithm" (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: (((("post clustering algorithm") OR ("data modeling algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"post clustering algorithm\") OR (\"data modeling algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( post clustering algorithm ) OR ( data modeling algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("post clustering algorithm") OR ("data modeling algorithm"))) OR ("relevant data algorithm"))*.
