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