Automatically fill search fields in Infopath List Form 2013

Environment: SharePoint 2013
Application: Infopath List Form 2013
We have a list (Suppose ListA) with different search columns from different lists, and we connect a list (ListA) as a data connection to the infopath list.
And we'll need an autofill if Dropdown is selected in Infopath List Form (if Dropdown is selected, the search box values ​​must be set accordingly).
Please help us to fulfill the requirement.
Thank you in advance.
