Searching using memberlist.php (Direct search)

[T3MEDIA]

memberlist.php can be used to do searches using the do=getall& command right.
Now I have a field called field6[0] Now this field is races. Black white brown etc.

When I do a search for say white. I get every user that has that feature selected. How do I go about having it show only users that have that field selected only?

As of now if you have white & black selected you will pop up in this search.
I find it is almost inverted (lack of a better word) searching.
I mean if I wanted white & black I would click white checkbox and black check box then I can get users who are white, both or black.

as it is now it will show ONLY users that are both.

I am almost positive I have to put a command string in the URL. So I came here for help.

the string I have now is:

memberlist.php?do=getall&page=1&agefrom=0&ageto=0&hasprofilepic=on&ltr=&pp=100&order=desc&postslower=0&postsupper=0&sort=joindate&ausername=&homepage=&icq=&aim=&yahoo=&msn=&joindateafter=&joindatebefore=&lastpostafter=&lastpostbefore=&field6[0]=6

Thanks.
