Autodesk Labs has released a technology preview for Content Search. Please give it a try and let the Labs team know what you think: Labs.ContentSearch@autodesk.com.
You can use text search capabilities to locate DWF files (as well as other formats such as PDF or DWG). In the case of DWF, you can view the design data using Autodesk Freewheel. If you like what you see, you can download the design data in one of the available file formats and include it in your own designs. Since Autodesk Freewheel requires only a browser, you can locate design data without having the design authoring application. With this ease of access, DWF definitely goes beyond the paper.
