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