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_single algorithm" (Expand Search)
"element method algorithms" » "element two algorithms" (Expand Search), "element other algorithms" (Expand Search), "element tested algorithms" (Expand Search)
"element both algorithms" » "element art algorithms" (Expand Search), "element four algorithms" (Expand Search), "element box algorithm" (Expand Search), "element data algorithms" (Expand Search), "element te algorithms" (Expand Search), "element mesh algorithms" (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: (("image 1_using algorithm") OR ((("element both algorithms") OR ("element method algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image 1_using algorithm\") OR (((\"element both algorithms\") OR (\"element method algorithms\"))))".
• Removing quotes may allow a broader search: (( image 1_using algorithm ) OR ((( element both algorithms ) OR ( element method algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image 1_using algorithm") OR ((("element both algorithms") OR ("element method algorithms"))))*.
