How to count IPs that match fields in two different searches?

I need to create a search that counts IPs which return events for two different fields in the same index. Search 1 will not contain field1=ABC when Search 2 contains field2=123

Search 1:

index=weblogs field1=ABC

Search 2:

index=weblogs field2=123

If I understand the question correctly, this may get you started.

index=weblogs (field1=ABC OR field2=123)
| stats dc(IP)
---

I think this will count if the IP has returned one of these fields, but I need to determine the number of unique IPs that have hit both of these fields.

You'll want this then

index=weblogs (field1=ABC OR field2=123)
| stats dc(field) as fieldOccurrence by IP
| where fieldOccurrence=2

This is counting how many fields there are by IP and then filtering out only those with both field occurrences.

Hope this helps.

Thank you for the response!

I may not be explaining this quite well, but I'll try to be a little more specific for this scenario-

 

I need to determine in the web logs how many unique IPs have hit a specific URL (field1=ABC) and also have visited a URL that generates a certain value in field2. 

field1=ABC will not be present in the same log where field2=123. These logs are in the same index and sourcetype.

index=weblogs (field1=ABC OR field2=123)
| eval state=case(field1="ABC","field1",field2="123","field2")
| stats count(eval(state="field1")) as field1_count count(eval(state="field2")) as field2_count by IP

Your sample is wrong, can you fix it into an actual query?
