Your best bet really is to have Solr do this for you with distributed search. You can add the shards parameter to your queries easily with SolrJ, or you can do what I do: set up a special core on the server that includes the shards parameter in solrconfig.xml. I call this a broker core. http://wiki.apache.org/solr/DistributedSearch Some quick googling turned up the following SolrJ code snippet, which is only valid if the servers are on the same machine as the SolrJ code: query.setParam(shards, localhost:8080/solr/core0/,localhost:8080/solr/core1/); Thanks, Shawn
Re: Searching in multiple cores via SolrJ
Hm, and in the case of my cores have different schemes? Thanks in advance.

You might have to do all the heavy lifting yourself, after using SolrJ to retrieve the results. I will say that I have no idea -- there may be ways you can avoid doing that. I hope there are, but if so, someone else will have to respond. Thanks, Shawn
Re: Searching in multiple cores via SolrJ
hmm... the less-horrible way I could think (if solr doesn't support it by default), is to create another core that mix the informations from other cores, and then, search in it. But, well, it would be ugly.

Re: Searching in multiple cores via SolrJ
Hi, I use solrJ for cross core search and it is work correctly and fast. At First, you can make attention on schema definition, you should try to use as much as possible fields with the same name. For example all my scheme have a subset of common fields like title, summary, date, geo, image, ecc.. and when you make the query you can use the param shards.tolerant=true When you do a query on a field that is present in a single core, Solr will return only documents of this core. I hope I helped you Bye - Complicare è facile, semplificare é difficile.
