Perhaps you should try some spelling variations:
"sediment sampling algorithm" » "sediment mining algorithm" (Expand Search), "sediment samples algorithm" (Expand Search), "sediment sample algorithm" (Expand Search)
"element erf algorithm" » "element rf algorithm" (Expand Search), "element em algorithm" (Expand Search), "element lr algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"element rl algorithm" » "element rl algorithms" (Expand Search), "element rf algorithm" (Expand Search), "element ml algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element _ 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: (("sediment sampling algorithm") OR ((("element rl algorithm") OR ("element erf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sediment sampling algorithm\") OR (((\"element rl algorithm\") OR (\"element erf algorithm\"))))".
• Removing quotes may allow a broader search: (( sediment sampling algorithm ) OR ((( element rl algorithm ) OR ( element erf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("sediment sampling algorithm") OR ((("element rl algorithm") OR ("element erf algorithm"))))*.
