Perhaps you should try some spelling variations:
"image 2_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 2_using algorithms" (Expand Search), "image 2_routing algorithm" (Expand Search), "image 2_fusion algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_single algorithm" (Expand Search), "image 2_long algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("data using algorithm") OR ("image 2_using algorithm"))) OR ("relevant data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data using algorithm\") OR (\"image 2_using algorithm\"))) OR (\"relevant data algorithm\"))".
• Removing quotes may allow a broader search: (((( data using algorithm ) OR ( image 2_using algorithm ))) OR ( relevant data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data using algorithm") OR ("image 2_using algorithm"))) OR ("relevant data algorithm"))*.
