How to prevent results from an input file being excluded after performing a lookup against another input

Hi,

I have the following search:

| inputlookup ldap_assets.csv
| lookup existing_assets dns output ip bunit category city country owner priority
| outputlookup create_empty=false createinapp=true override_if_empty=false merged_assets.csv

The 'ldap_assets.csv' contains a list of assets and their attributes. The search then does a lookup command on 'existing_assets' lookup which contains other asset attributes (a manually created list).  The search then outputs results to a merged_assets.csv. 

The problem im having is that if a record exists in existing_assets, but it doesnt exist in ldap_assets.csv, it is being excluded from results of the outputlookup command. I would like those existing records to still be included in the merged_assets.csv file. So basically I want the two files to merge without any exclusions after the lookup.

Can somebody provide assistance on where on going wrong?

Thanks.

Load the two files with two inputlookups, then merge the two data sets using stats values  grouping by the lookup fields.

| inputlookup ldap_assets.csv
| append [
  | inputlookup existing_assets
]
| stats values(*) as * by dns output ip bunit category city country owner priority
| outputlookup create_empty=false createinapp=true override_if_empty=false merged_assets.csv

 should do the trick

Thanks. Seems like the stats command is resulting in zero records. But turns out i dont need it.
