Perhaps you should try some spelling variations:
"algorithm python function" » "algorithms within function" (Expand Search), "algorithm both function" (Expand Search), "algorithm protein function" (Expand Search)
"algorithm within function" » "algorithm fibrin function" (Expand Search), "algorithm protein function" (Expand Search), "algorithm catenin function" (Expand Search)
"algorithm etc function" » "algorithm _ function" (Expand Search), "algorithm b function" (Expand Search), "algorithm a function" (Expand Search), "algorithm spc function" (Expand Search), "algorithm fc function" (Expand Search), "algorithm npc function" (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: (("algorithm within function") OR ((("algorithm python function") OR ("algorithm etc function"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"algorithm within function\") OR (((\"algorithm python function\") OR (\"algorithm etc function\"))))".
• Removing quotes may allow a broader search: (( algorithm within function ) OR ((( algorithm python function ) OR ( algorithm etc function )))).
• Adding a wildcard symbol may retrieve word variants: (("algorithm within function") OR ((("algorithm python function") OR ("algorithm etc function"))))*.
