Poser 11 does have a database, but it's not stupid LOL. It's only there to speed up searching and certainly not "needed" to use your content. It will crawl the linked runtimes so the search features work faster and the new Keyword categories work quickly,

Wait what? Keywords? Inside the library you can edit the keywords for any content. (In the extended details) Then in the search pane of the library use those keywords to quickly find content.
