Search by Invoice number

Hi,
I’m using the orders->find function but I just figured out that I would need to find invoices not orders. Not sure if there is a direct way to it!
Would you guys point me in the right direction?
Thank you

Our XML/RPC API can query Invoice data. I would start with https://developer.infusionsoft.com/docs/xml-rpc/#data-retrieve-a-record and the tableName is Invoice (https://developer.infusionsoft.com/docs/table-schema/)
