Splunk Search

lookup from different source types based on a common value

I want to search from multiple sources having one field in common and the query should return all the fields from both the sources..
Just like the vlookup function in excel..
e.g. i have two csv's having following data
csv-1 - IP Address, User Name
csv-2 - IP Address, Host Name
now the query should lookup for the common IP Address in both the csv's and return the result having following columns:
IP Address, Host Name, User Name

Assuming you have the files in the correct lookup location and named accordingly:

your_search | lookup csv-1.csv IP_FIELD_IN_CSV AS IP_FIELD_IN_SEARCH OUTPUT USERNAME_FIELD_IN_CSV | lookup csv-2.csv IP_FIELD_IN_CSV AS IP_FIELD_IN_SEARCH OUTPUT HOSTNAME_FIELD_IN_CSV | stats count by IP_FIELD_IN_SEARCH HOST_NAME_FIELD_IN_CSV USERNAME_FIELD_IN_CSV

ah ok, so you aren't using lookups, I misunderstood. Transaction and where is an expensive command, try this:
sourcetype=A OR sourcetype=B | stats values(hostname) values(username) by clientip

Thanks "alacercogitatus" for the reply..
however I got my query resolved with the following condition:
"transaction parameter-A parameter-B connected=f | where parameter-A=parameter-B"
