Perhaps you should try some spelling variations:
"elemental mining algorithm" » "elemental cosine algorithm" (Expand Search), "elementary mining algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "element mining algorithm" (Expand Search)
"text using algorithms" » "text cosine algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling 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: (("elemental mining algorithm") OR ((("text using algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elemental mining algorithm\") OR (((\"text using algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elemental mining algorithm ) OR ((( text using algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elemental mining algorithm") OR ((("text using algorithms") OR ("neural coding algorithm"))))*.
