We describe XTreeNet, a distributed query dissemination engine which facilitates democratization of publishing and efficient data search among members of online communities with powerful full-text queries. This demonstration shows XTreeNet in full action. XTreeNet serves as a proof of concept for democratic community search by proposing a distributed novel infrastructure in which data resides only with the publishers owning it. Expressive user queries are disseminated to publishers. Given the virtual nature of the global data collection (e.g., the union of all local data published in the community) our infrastructure efficiently locates the publishers that contain matching documents with a specified query, processes the complex full-text query at the publisher and returns all relevant documents to querier.
