The navbar search on the home page, which uses the ?keyword URL parameter, is not returning results. Example "Edessa": https://d2tcgfyrf82nxz.cloudfront.net/search.html?keyword=Edessa.
I think it should use the ?fullText parameter, like the "Keyword in Any Language" field from advanced search (this is also how the navbar works in the main browse.html page, https://d2tcgfyrf82nxz.cloudfront.net/browse.html)
