*etc*  = removed text for anonymity  
 I have a very complex search query that input the following table:  
Network , Source_IP, count  
 Search for this:  
  sourcetype="etc" index=*etc* EventCode=*etc* field46="*" | rex field=field46 "(?\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\:)(?\d+)\s+(?.*)" | dedup ip network | stats values(ip) as Source_IP dc(ip) as count by network   | sort count desc | table network count |  head 100
  
 I need to match  Network with an inputlookup file column account. Join/append? Not sure. The inputlookup file looks like this:   
Account, department, environment, primary, secondary  
 The final output needs to show the initial results with added columns = account, primary and secondary data from the inputlookup file. For those with no match, then it just need to show NULL in those 3 new columns.  
 Final Output Sample:   
network, department, primary, secondary, source_IP, count   
testuser , null, null, null, 10.10.10.10, 500   
testuser1, team2, director1, director2 , 100.10.10.10, 10   
testuser3, team4, director3, director4 , 100.10.10.10, 8
