Perhaps you should try some spelling variations:
"wood processing algorithm" » "food processing algorithm" (Expand Search)
"end processing algorithm" » "rna processing algorithm" (Expand Search), "food processing algorithm" (Expand Search), "text processing algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore 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: (("element rf algorithm") OR ((("wood processing algorithm") OR ("end processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element rf algorithm\") OR (((\"wood processing algorithm\") OR (\"end processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element rf algorithm ) OR ((( wood processing algorithm ) OR ( end processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element rf algorithm") OR ((("wood processing algorithm") OR ("end processing algorithm"))))*.
