NOTE:
Index name limitations
There are several limitations to what you can name your index. The complete list of limitations are:
Lowercase only
Cannot include , /, *, ?, “, <, >, |, ` ` (space character), ,, #
Indices prior to 7.0 could contain a colon (:), but that’s been deprecated and won’t be supported in 7.0+
Cannot start with -, _, +
Cannot be . or ..
Cannot be longer than 255 bytes (note it is bytes, so multi-byte characters will count towards the 255 limit faster)
