Multiple parameters in REST API

Hi,

https://XXXX-test.fa.em3.oraclecloud.com/fscmRestApi/resources/11.13.18.05/standardReceipts?q=ReceiptNumber=MIG1220&CustomerAccountNumber=808500

When I pass one parameter it works fine but with two parameters I get the error as

URL request parameter CustomerAccountNumber cannot be used in this context.

Thanks
