Unique custom field

Hi,

When I index my content, one of the fields I store is a MD5 hash sum of another field.

I don't want this field to be used as the "key", but when I search I want to specify that I don't wany duplicate results for this field.

Is there a way to do that?

Thanks,
Dan

You could try field collapsing as a way to group fiels with identical
signatures together and only display one of the results....

Best
