- You can now put a $ at the end of a search term to force the search engine to treat it as a tag and do an exact search rather than searching all tags that start with the term. This works both with and without a namespace.
Thanks, this'll make certain things with cleanup much easier!
But I found something. The faux-namespace "uploader" does not behave well with $. This wouldn't be a problem in almost all situations, but when going from an uploader's plain search results
https://e-hentai.org/uploader/StatisticallyNPand then clicking on "Display Thumbnails" or "Display List", $ is added to the end and the search fails because "uploader" is not a real namespace. I think. It might be due to the "&f_exact=1" in the link on the /uploader/* page, since when that is removed it seems to change the display type as expected and use the correct "uploader:" string without $.
Uploader:usernames with spaces also fail, but it's a bit worse.
https://e-hentai.org/uploader/no%2Bcondom...253D%2Bno%2Bsexuploader:"no condom = no sex"
turns into
no condom = no sex"$" uploader:""
Same problem, same solution.
Ordinary searching for "uploader:" looks to be OK because there's no "&f_exact=1".
