Can you help me create a search that would match fields for two different indexes and stats?

Hi team!

I need help with a search.

I have 2 indexes and I want to match both for an IP field. If they match, I want stats for the first one.

This is my search right now.

(index=AAA Ip=*) OR (index=BBB src_ip=* (threat_name="SCAN: Host Sweep(8002)" OR threat_name="SCAN: TCP Port Scan(8001)" OR threat_name="TCP Flood(8501)" OR threat_name="UDP Flood(8502)" OR threat_name="TCP SYN with data(8723)") (src_zone!="Inet-WAN1" AND src_zone!="Inet-WAN2") (dest_zone!="Inet-WAN1" AND dest_zone!="Inet-WAN2") src_ip != 191.100.200.27 AND src_ip != 191.100.200.71 AND src_ip != 191.100.200.56) | eval match_ip=coalesce(Ip,src_ip) | stats values(*) AS * by match_ip | search src_ip=* Ip=* | stats count, values(src_zone) as Source_zone,values(dest_zone) as Destination_zone, values(threat_name) as "Threat name", values(vendor_action) as Action, values(severity) as Severity by user,src_ip, generated_time, dest_ip |table generated_time,"Threat name", Action,Severity src_ip, dest_ip,user, Source_zone, Destination_zone | rename src_ip as Source_IP, dest_ip as Destination_IP, user as User, generated_time as Date

Right now it finds the match IP. But the problem is it didn't show the fields well. I should have 55 events and I have 2000. Every IP has multiple times, dest zones etc. Obviously, this is not true.

Thank you!

Maybe using a subsearch? It has limits but for small amounts of data or time ranges it is fine.

index=AAA 
    [search index=BBB ... 
    | stats count by src_ip
    | table src_ip
    | format]
| ...etc
