Hi, Teodor Sigaev wrote:
Word number is used only in ranking functions. If you don't need a ranking than you could safely strip positional information.
Huh? I explicitly *want* positional information. But I find the word number to be less useful than a character number or a simple (byte) pointer to the position of the word in the string.
Given only the word number, I have to go and parse the string again. Regards Markus
