Can anyone tell me whether support for distributed search is added to
QueryElevationComponent in solr 4.0 ? 

I looked at QueryElevationComponent code in trunk and it doesnt seem to have
any code to support distributed search. Am I missing something here ?

Yes.

Because of the way it's done, you are missing it - doesn't require many of the 
std distrib methods to be impl'd - mostly involves improvements to the custom 
sort stuff.

Hi Mark

Thanks a lot for your response.  Yeah, I was looking for distributed
methods. I would like to know the reason why it didn't work in Solr 3.6.
When i try (i only have solar 3.6)

Note: the same query below works when i replace elevate with select, by
which i am assuming my setup is correct. 

http://localhost:8080/solr/shard1/elevate/?q=dressdebugQuery=trueshards=localhost:8080/solr/shard1,localhost:8080/solr/shard2

I get the error 

Problem accessing /solr/shard1/elevate/. Reason:

It would be great if you can give me an overview of how its fixed in solr
4.0. Is it with the modifications to the ElevationComparatorSource class ?

Thanks

QueryElevationComponent and distributed search

2012-04-24 Thread srinir 
Hi,

I am using solr 3.6. I saw in Solr wiki that QueryElevationComponent is not
supported for distributed search. 

https://issues.apache.org/jira/browse/SOLR-2949

When I checked the above ticket, it looks like its fixed in Solr 4.0. Does
anyone have any idea when a stable version of solr 4.0 will be released
(approx time frame). If not, are these changes independent to other solr 4.0
changes that i can just copy this patch to my setup for now? I would like to
use solr 3.6 because i would like to use a stable version in production.


Thanks
Srini
