Hi,

I'm using ES 1.7, and I have 2 indexes:

1. names & address
2. address list

I want to compare this two, and if the address from index 1 exits in index 2, an additional field will be added to index 1 stating that the address exists.

For example:  
name =\> "John Snow", address =\> "Winterfell"

Now if the address "winterfell exists in index 2, than index one will change to:  
name =\> "John Snow", address =\> "Winterfell", exists =\> "True"  
Otherwise:  
name =\> "John Snow", address =\> "Winterfell", exists =\> "False"

How do you recommend to do this?

Thanks

You cannot do this via any direct ES queries, you'd need to do this entirely in code, external to ES.
