Apache Solr Search connector upon Windows Search -- 2

Let's say I've got a Solr core installed on a windows desktop. Let's say I want to keep Solr compliant because my web interface uses SolrJ. The goal of my app is to crawl lot of different sources with Solr later in the future (e.g: FS, Intranet, Emails, etc.). Also to keep the maximum of performances on the Windows OS, I want to use the native Windows Search indexing rather to use Solr for indexing the whole Windows File System. But I don't know how to bind the Windows Search layer from the Solr search on the top. Does anybody could develop a search connector source code for Solr (in java) to delegate the queries from Solr to Windows Search (e.g: via OpenSearch for example) ? Note that the only link I've found is : [login to view URL] Thank's a lot.
