Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element three algorithms" » "element based algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements ree algorithms" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element model 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: (("client sampling algorithm") OR ((("element ore algorithm") OR ("element three algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client sampling algorithm\") OR (((\"element ore algorithm\") OR (\"element three algorithms\"))))".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element ore algorithm ) OR ( element three algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element ore algorithm") OR ("element three algorithms"))))*.
