[Mediawiki-l] mediawiki 1.4 & 1.5rc4, substring search, how?

[Maurice Joseph]

Andrew;

Yes.

function legalSearchChars() {
	return "A-Za-z_'*0-9\\x80-\\xFF\\-";
}

It looks like this string is treated as a class in a regular expression in the 
filter function.

It would be more practical to parameterize this is DefaultSettings.php for 
those who wish to modify without changing code.

Let me know if you encounter any side affects.
