Perhaps you should try some spelling variations:
"cost price" » "just price", "list price", "lowest price"
"costa rice" » "costa ricas", "costs price", "costa rita"
"costa rica" » "costa rich", "costa rita"
"costa rican" » "costa richn", "costa ritan"

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: (("costa rica") OR ((((("costa rice") OR ("cost price"))) OR ("costa rican")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"costa rica\") or (((((\"costa rice\") OR (\"cost price\"))) or (\"costa rican\"))))".
• Removing quotes may allow a broader search: (( costa rica ) or ((((( costa rice ) OR ( cost price ))) or ( costa rican )))).
• Adding a wildcard symbol may retrieve word variants: (("costa rica") or ((((("costa rice") OR ("cost price"))) or ("costa rican"))))*.
