- browsing through the web came I accross an application called the Lucene Web Service : what do you think of it ? (its goal seems precisely to query multiple indices, it thus would be the thing I'm searching for ; but considering the scale of this project, I think I'd prefer to base my work on a project the long time activity of which is guaranted, such as Solr)
Lucen Web Service still exist : http://www.opensearch.org/Home
You can specific tag in your namespace if it's not already exist. M.
