Perhaps you should try some spelling variations:
"sediment samples algorithm" » "sediment sampling algorithm" (Expand Search), "sediment kepler algorithm" (Expand Search), "sediment atlas algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"elements b algorithm" » "elements _ algorithm" (Expand Search), "elements box algorithm" (Expand Search), "elements dbo algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element g 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 method algorithm") OR ("elements b algorithm"))) OR ("sediment samples algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"elements b algorithm\"))) OR (\"sediment samples algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( elements b algorithm ))) OR ( sediment samples algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("elements b algorithm"))) OR ("sediment samples algorithm"))*.
