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