Hi,

I have two indices:

1. info-source
2. info-destination

Both the indices have a few similar field. One such field is the `ip` field.

I wish to write a query that will give me a list of `ip` present in both indices. Can this be accomplished in **elasticsearch**? Currently I am doing this in Python, but this adds an overhead which I wish to avoid. Please help.

Regards,  
N

It's not. Unless you use parent / child feature

BTW read [this](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and specifically the "Also be patient" part.

It's fine to answer on your own thread after 2 or 3 days (not including weekends) if you don't have an answer.
