We're working on getting omeka set up for a historical project that we're working on, and some of our librarians have been dutifully tagging and describing items in our collection. However, one of the librarians just tried to search for a tag she knew existed on an item, and nothing comes up when she searches by tags. Are tags not included in the text of a keyword search? Is there a way that I can make this so? It seems useless to have tags if the results don't show up in search!
