Description

The method

private static int ordinalIndexOf(final CharSequence str, final CharSequence searchStr, final int ordinal, final boolean lastIndex) 

source
at the line

1028                index = CharSequenceUtils.indexOf(str, searchStr, index + searchStr.length());

is using as starting index for search the index+searchStr.length() .In case where the searchStr is a single character, the first run will start from index

-1+1 = 0

if the searchStr is long N, it will start at N-1 index and if str contains the searchStr before N-1 it will miss it
