Use eval field inside append search

[mad_splunker]

Hello Splunkers,

I am trying below query -

index=someindex cluster=gw uuid=gw98037234c6e51a48816016172b8a3c56
| eval api_uuid="gw"+reqid
| head 1
| append [search index=someindex cluster=api uuid=api_uuid]

Basically what I am trying is to get result from first search, evaluate new field from first search and add it as condition to second search. It is not working if I supply api_uuid field but If I replace uuid in append with actual computed value it is returning proper result. I have seen few people using join but dont want to use join as its expensive and comes with limit. Any solution to above query ?

index=someindex cluster=api uuid=api_uuid [ search index=someindex cluster=gw uuid=gw98037234c6e51a48816016172b8a3c56 | eval uuid="gw"+reqid  | table uuid ]

Can you please try this? I have used different approach. 

thanks
