Perhaps you should try some spelling variations:
"sediment sampling algorithm" » "sediment mining algorithm" (Expand Search), "sediment samples algorithm" (Expand Search)
"sediment sample algorithm" » "sediment carlo algorithm" (Expand Search), "sediment svm algorithm" (Expand Search), "sediment kepler algorithm" (Expand Search), "sediment samples algorithm" (Expand Search), "sediment supply 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 ((("sediment sampling algorithm") OR ("sediment sample algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element rf algorithm\") OR (((\"sediment sampling algorithm\") OR (\"sediment sample algorithm\"))))".
• Removing quotes may allow a broader search: (( element rf algorithm ) OR ((( sediment sampling algorithm ) OR ( sediment sample algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element rf algorithm") OR ((("sediment sampling algorithm") OR ("sediment sample algorithm"))))*.
