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 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: (((("element ore algorithm") OR ("element five algorithms"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ore algorithm\") OR (\"element five algorithms\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element ore algorithm ) OR ( element five algorithms ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ore algorithm") OR ("element five algorithms"))) OR ("client sampling algorithm"))*.
