ar invoice search ai agent - want to search on customer name and trans date but it doesn't work

ar invoice search ai agent - want to search on customer name and trans date but it doesn't work. It will only gives me transactions from 2017 to 2023. I can get search for transaction number to work but it seems like it is having hard time with customer name(billtocustomername) and only does first pages. i have tried /fscmRestApi/resources/11.13.18.05/receivablesInvoices?limit=100&onlyData=true and /fscmRestApi/resources/11.13.18.05/receivablesInvoices?q=CustomerName='{pCustomerName}';TransactionDate>={pFromDate};TransactionDate<={pToDate}&onlyData=true. Can you search on billtocustomername and transdate or is that too large of a search?
