Perhaps you should try some spelling variations:
using function » using functional (Expand Search), sine function (Expand Search), waning function (Expand Search)
algorithm api » algorithm ai (Expand Search), algorithm a (Expand Search), algorithm i (Expand Search)
algorithm spc » algorithm etc (Expand Search), algorithm pca (Expand Search), algorithm seu (Expand Search)
api function » a function (Expand Search), i function (Expand Search), adl function (Expand Search)
spc function » gpcr function (Expand Search), fc function (Expand Search), _ function (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( algorithm api function ) OR ( algorithm using function ))) OR ( algorithm spc function ))~".
• Adding a wildcard symbol may retrieve word variants: (((( algorithm api function ) OR ( algorithm using function ))) OR ( algorithm spc function ))*.
