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 1_using algorithm" (Expand Search), "image 2_single algorithm" (Expand Search), "image 2_long algorithm" (Expand Search)
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"element cscap algorithm" » "element cc3d algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element custom 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: (("image 2_using algorithm") OR ((("element cscap algorithm") OR ("element network algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image 2_using algorithm\") OR (((\"element cscap algorithm\") OR (\"element network algorithm\"))))".
• Removing quotes may allow a broader search: (( image 2_using algorithm ) OR ((( element cscap algorithm ) OR ( element network algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image 2_using algorithm") OR ((("element cscap algorithm") OR ("element network algorithm"))))*.
