Hi,  
I have a system that containe 5 clusters in 6.2.4.  
4 clusters which containe data, and one cluster which have three coordinating nodes.  
I use the option of cross cluster search in order to search from the coordinating cluster on all the other four, and return one result.  
I configure the coordinating cluster in the following way:  
Cluster\_one:  
Seeds:a,b,c  
Cluster\_two:  
Seeds:d,e,f  
Cluster\_three:  
Seeds:g,h,i  
Cluster\_four:  
Seeds:j,k,l

When i want to search, i execute a search on fhe coordinating cluster in the folowing order:  
Cluster\_\*:\<name\_of\_the\_index\>

I got a good results, but when i execute a search like that:  
Cluster\ __:\<name\_of\_an\_index\_in\_cluster\_one\>, Cluster\__ :\<name\_of\_an\_index\_in\_cluster\_two\>

I got zero results.

Thanks in advance.

When you use `Cluster_:<name_of_an_index_in_cluster_one>, Cluster_:<name_of_an_index_in_cluster_two>` , I think you should specify the complete cluster alias rather than just `Cluster_`. Otherwise add a wildcard like you did in the previous attempt. If there's no remote cluster matching a prefix, we treat the index like a local index. Hopefully that is the problem.

Cheers  
Luca

I am sorry, i forgot to mention that i use wildcard in here also.  
Cluster\ __:\<name\_of\_an\_index\_in\_cluster\_one\>, Cluster\__ :\<name\_of\_an\_index\_in\_cluster\_two\>
