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

Try widening your search to All Fields.

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 base") OR ((("shape add") OR ("shapes add"))))) OR ("shape grab")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"shape base\") or (((\"shape add\") OR (\"shapes add\"))))) or (\"shape grab\"))".
• Removing quotes may allow a broader search: (((( shape base ) or ((( shape add ) OR ( shapes add ))))) or ( shape grab )).
• Adding a wildcard symbol may retrieve word variants: (((("shape base") or ((("shape add") OR ("shapes add"))))) or ("shape grab"))*.
