I want to set account_debit to '5848' if there is one, otherwise set the account to '5800'

<record id="hr_salary_rule-sau" model="hr.salary.rule">
    <field name="account_debit" search="['|',('code', '=', '5848'),('code', '=', '5800')]" />
</record>

But i think the Postgres optimizer uses the order of code in account.account rather than care about the order of precedence.

Is there a way to do this? Change the order by? Conditions in the XML?
