As an example, let's say I have 100 contacts. 20 are church contacts, so under their names in their contacts entry in the company line, I enter 'church'. If I want to find someone in this church group, I only need to enter 'church' in the contacts search box, and all entries in that group appear in a list. Some contacts belong to more than one group, eg, church and neighbour. As long as I have both group search terms listed in the contacts info, they will show up in the search. You don't need to search specifically for a company name, just the name of the group. Sorry if I am misunderstanding what it is you are trying to do.
