Perhaps you should try some spelling variations:
"shaped bases" » "shaped based", "shaped blades", "shaped laser", "shaped baseds", "shape bases", "shaped lasers"
"shaped base" » "shaped based", "shape base", "shaped laser"
"shape gas" » "shape base", "shape grab", "shape a"

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