Multicore and TermVectors

Hello.

My new to solr and I'm trying to setup solr with a multicore configuration.
All cores shares the same schema.xml and I'm using index sharding.

I need term vectors data to generate tag clouds but when I try to run a search across all cores to retrieve term vectors data the engine 
raises me the exception below.

Now I created two request handlers, one for the user search and one for the engine in charge to create the tag cloud. The problem of this 
solution is that I've to run n queries if n cores are cofigured and than merge results

thanks in advance
christian f.

There is no query parameter. The query parser throws an NPE if there
is no query parameter:

http://issues.apache.org/jira/browse/SOLR-435

It does not look like term vectors are processed in distributed search anyway.

It doesn't sound like Multicore is your issue ... it seems like what you 
mean is that you are using distributed search with TermVectors, and that 
is causing a problem.  Can you please clarify exactly what you mean ... 
describe your exact setup (ie: how manay machines, how many solr ports 
running on each of those machines, what the solr.xml looks like on each of 
those ports, how many SolrCores running in each of those ports, what 
the slrconfig.xml looks like for each of those instances, which instances 
coordinate distributed searches of which shards, what urls your client 
hits, what URLs get hit on each of your shards (according to the logs) as 
a result, etc... 

details, details, details.
