The ASCII character set

The text search engine uses the ASCII character set by default.

The text search engine uses this table to translate just the alphanumeric characters in the ASCII set (0 through 9, A through Z, and a through z). The lowercase characters are translated to uppercase, so this table results in 36 possible unique character values.
