Hi Partner,
You need edit columns of the account table's Quick Find View.
The Find Columns on a Quick Find View define the searchable fields in the Dataverse search index. Text fields such as Single Line of Text and Multiple Lines of Text, Lookups, and Option Sets are searchable. Find Columns of all other data types are ignored.
The View Columns on a Quick Find View define the fields that are displayed in model-driven apps' search results page when the matched results are returned.
Quick Find Active Accounts view
Currently OOB can't show more than two fields:
1)one column is the default column which is nothing but a Primary column of a table;
2)the Secondary column will choose based on the table’s quick find view, it is always the first non-primary column on the table’s quick find view that contains data.
3)The search column contains the searched values and will replace the other columns in the second column.
I hope you can mark my answer verified if it is helpful! If you have any questions, please feel free to contact me.
Regards,
Leah
