Distributed search

Hi,

Can we use multicore to have several indexes per webapp and use distributed
search to merge the indexes?

for exampe if we have 3 cores -core0 ,core1 and core2 for 3 different
languages and to search across all the 3 indexes
use the shard parameter as
shard=localhost:8080/solr/core0,localhost:8080/solr/core1,localhost:8080/solr/core2

Regards
Sujatha

Distributed search requires that all of the shards have "compatible" 
schemas ... some shards can have more or less fields then other shards, 
but only if those fields don't get used as part of the distributed 
request.

so while you could do something like this, it won't neccessarily work the 
way you want it if those 3 cores have differnet schemas.

Yes you should fire the request to an existing core.

Hi,
	I am trying distributed search and multicore but not able to fire a query. I tried 
http://localhost:8080/solr/select/?shards=localhost:8080/solr/core0,localhost:8080/solr/core1&q=solr
I am getting following error: "Missing solr core name in path". 

Should I use particular core to fire distributed search?

Hi,

That should work, yes, though it may not be a wise thing to do performance-wise, if the number of CPU cores that solr server has is lower than the number of Solr cores.
