Perhaps you should try some spelling variations:
"data sorting algorithms" » "data routing algorithm" (Expand Search), "data learning algorithms" (Expand Search), "data working algorithms" (Expand Search), "data supporting algorithms" (Expand Search), "data settings algorithms" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"gmm clustering algorithm" » "_ 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 sorting algorithms") OR ("gmm clustering algorithm"))) OR ("relevant data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data sorting algorithms\") OR (\"gmm clustering algorithm\"))) OR (\"relevant data algorithms\"))".
• Removing quotes may allow a broader search: (((( data sorting algorithms ) OR ( gmm clustering algorithm ))) OR ( relevant data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data sorting algorithms") OR ("gmm clustering algorithm"))) OR ("relevant data algorithms"))*.
