Perhaps you should try some spelling variations:
"element scraping algorithm" » "element sampling algorithm" (Expand Search), "element tracking algorithm" (Expand Search), "element making algorithm" (Expand Search), "element strain algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"client leiden algorithm" » "client learner algorithm" (Expand Search), "client kepler algorithm" (Expand Search), "client mean algorithm" (Expand Search)
"client needs algorithm" » "client means algorithm" (Expand Search), "client new algorithm" (Expand Search), "client fedsam algorithm" (Expand Search), "china needs algorithm" (Expand Search), "urgent needs 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 scraping algorithm") OR ((("client needs algorithm") OR ("client leiden algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element scraping algorithm\") OR (((\"client needs algorithm\") OR (\"client leiden algorithm\"))))".
• Removing quotes may allow a broader search: (( element scraping algorithm ) OR ((( client needs algorithm ) OR ( client leiden algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element scraping algorithm") OR ((("client needs algorithm") OR ("client leiden algorithm"))))*.
