Probably as a result of $HEX[] wars, there are many "broken" hashes in the database that do not return valid results. For example, try looking up any of these:
4b19def466c2e3b169259c0a201a289a
4d8205b78abaaa20306152b72777b34e
628fa9ed72fd8167e18874c98850aa98
6c7d06d82154905bd7f01f9b22887228
b28291fa39030fd447c605947517652f
d4e7eaf872bf9173e8db4d3aaea9852c
ff6a82e52ee5ecc14f55ef21da6972ee
You will get a found result of ":". Likely these hashes are of plaintext that has nulls or other unprintable characters embedded - thus the original reason I introduced $HEX[] encoding.
I don't know how many others are this way, unfortunately. I'm happy to help debug this, if you need help.
