Apache Solr Search connector upon Windows Search

Let's say I've got a Solr core installed on a windows desktop, I want to keep Solr compliant because my web interface uses SolrJ. The goal of my app is to crawl lot of different sources later in the future (e.g: FS, Intranet, Emails, etc.). Also to keep the maximum of performances, 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 (with OpenSearch ?) with the Solr search on the top. Does someone could develop a search connector for Solr (in java) to delegate the queries to the Windows Search (e.g: via OpenSearch for example) ? Thank's a lot.
