How to compare event data with lookup data to find missing field values?

I need to compare the values of 2 fields from the Splunk data with the field-values from the lookup and find the missing values from the Splunk data and output those missing field value pairs

For ex:

index=test  sourcetype=splunk_test_data
fields: field1, field2

lookup: test_data.csv
Fields: field1, field2

The output should show missing values from the Splunk data and output those missing values

Any help would be appreciated 
Thanks

To find out which fields are present in the lookup and absent in the index use a subsearch, like this:

| inputlookup test_data.csv where NOT [search index=test sourcetype=splunk_test_data | fields field1 field2 | format]

The same search should do that.  It's a matter of how extensive the lookup file is.
