Suppose I've created two smart groups and I want to search for contacts who are members of both of them. In Search > Search Builder I select

Record type: Individual
Field: Group(s)
Operator: IN

then type the group ID number in the box. This search returns the members of the relevent group. But if I add a second search field, identical except with a different group ID number, to search for only those records which are in both the specified groups, the search returns no matches, even though I have explicitly checked that some records are in both of the relevant groups. For both the single and double group searches I describe I get the following warning message:

"Notice: Undefined index: group in CRM_Contact_Selector->getColumnHeaders() (line 446 of /var/www/speak.org.uk/sites/all/modules/civicrm/CRM/Contact/Selector.php)."

I don't know whether or not that warning has anything to do with the problem I'm experiencing.  Any ideas what's going wrong?

Yep. The custom search posted by Lobo works to mitigate group exclusion perfectly for me.
Oh how I wish I'd looked at the ALL the custom searches before instead of giving up after a few broken ones.

As it turns out, none are broken.
I believe I was just really green at my first attempt and did not really understand what I was trying to chieve with the custom searches.
