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