Probably if you edited the contacts to include their company name, city or state in their contact info.....although I've never tried this I cannot say for sure that this will work, but it would be worth a try
EDIT: Just tried this out with a doctors office I had in my contacts.........I put Medical as the Organization, Doctor as the Position, and in the Notes section, I put the town in which its located......
In my Google Search bar widget, a search for "doctor" turned up the contact, but a search for "medical" or the town in which its located was negative on bringing the contact up in the results....perhaps if you put the most important info in the Position field, you could organize the contacts in which you could search for them......
Hope this helps!
