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