Perhaps you should try some spelling variations:
"shapes add" » "shapes a", "shapes 3d", "shapes adding"
"shape base" » "shaped base", "shapes based", "shaped based"
"shape based" » "shaped based", "shapes basedd", "shaped basedd"
"shape add" » "shape a", "shape 3d", "shape 1d"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("shape add") OR ("shapes add"))) OR ((("shape base") OR ("shape based")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"shape add\") or (\"shapes add\"))) or (((\"shape base\") OR (\"shape based\"))))".
• Removing quotes may allow a broader search: (((( shape add ) or ( shapes add ))) or ((( shape base ) OR ( shape based )))).
• Adding a wildcard symbol may retrieve word variants: (((("shape add") or ("shapes add"))) or ((("shape base") OR ("shape based"))))*.
