How to combine two field values into one

[skodak]

I have got a query like this

index=* request in (request1, request2, request3)

eval  request&& = request1 + request2

Please help.

Based on your query I understand that request1,request2,request3 are values of request. 
eval you are adding request1,request2 you will get empty because you don’t have those fields.

share sample event and explain your question clearly.

Looks like I got the solution.  I have used MATCH  to solve it.

Thank you @thambisetty
