match_type wildcard not working for automatic lookup

Please any help will be appreciated.
We have a lookup test_pci_asset.csv with a field nt_host
values of nt_host are host1 host2

Raw log in splunk host fields are host1.abc.com

We are trying to use automatic lookup to match the host field so when we run a query it can pull back host1.abc.com as host.
We tried the following with WILDCARD(nt_host) but no luck. Props and transforms below

props.conf
[default]
LOOKUP-test_pci_asset.csv = test_pci_asset nt_host AS host OUTPUTNEW bunit category city ip owner

transforms.conf
[test_pci_asset]
batch_index_query = 0
case_sensitive_match = 0
filename = test_pci_asset.csv
match_type = WILDCARD(nt_host)

Your lookup needs to contain the wildcard.
Enter the hosts in your lookup file as host1*, host2*

You cannot get features of a lookup definition if you reference the filename.csv. Create the lookup definition then use that name in the lookup command.

Thank you @nickhills

|inputlookup pci_asset_lists.csv | eval nt_host=nt_host."*" | outputlookup pci_asset_lists.cs
I added * to the nt_host list with tquery above and still not working. Any ideas why?

You need to use the lookup definition. You can not use a CSV file directly for a wildcard search.

Test it works like this:

<your search> |lookup test_pci_asset nt_host as host OUTPUTNEW bunit category city ip owner

also - check the lookup is as you expect:
|inputlookup test_pci_asset do the hotsnames include *
