Is there any good exhaustive resource for finding idioms by theme? I tried to google some, but the ones I found on google are not very exhaustive. They have maybe 500 idioms in total. I currently use Wiktionary, but I can only search by the word they contain, which isn't very useful.
This one seems to be the best on the Internet, but it's a far cry from what I would like to find:
