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 algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore 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 method algorithm") OR ("element tree algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image 1_using algorithm\") OR (((\"element method algorithm\") OR (\"element tree algorithms\"))))".
• Removing quotes may allow a broader search: (( image 1_using algorithm ) OR ((( element method algorithm ) OR ( element tree algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("image 1_using algorithm") OR ((("element method algorithm") OR ("element tree algorithms"))))*.
