KAddressBook in a previous version used to be able to merge contacts. The new version does not have any way to do this.
Two contacts cannot even be merged manually in any easy way, because only one contact's details can be displayed and/or edited at a time. So the only way to do it in KAddressBook is to either print one contact our and re-enter the info from paper while doing a manual merge, or by juggling the contact editor window open and closed over and over many times for each piece of information.
Currently, the fastest way I have found to merge contacts is to export as vCard, merge with a different program, then delete everything in KAddressBook and reimport the externally merged vCards. This is suboptimal to say the least!
Steps to Reproduce:
1. Create a lot of contacts with names, multiple e-mail addresses, and IM information (e.g. imported from an e-mail program).
2. Create a lot more contacts about mostly the same people, but this time with just names, phone numbers, and mailing address (e.g. imported from another address book application)
3. Look for an automatic "find and merge" and don't find it.
4. Try to highlight two contacts and manually select "merge", but see there is no such feature.
5. Attempt to merge them by hand.
6. (Do this for at least 100 contacts before saying this is no big deal.)
There is no feasible way to merge contacts, even by hand. It's easier to use another program, or even just edit the raw vCards with a text editor.
KAddressBook should have at least a way to highlight some contacts and hit "Merge", which lets you interactive resolve conflicts. Even better would be a smarter "find and merge" which asks the user if this should be done all fuzzy matches based on existing names or data.
Kontact is a top-of-the-line program in many respects, but KAddressBook not handling contact merges well (or really at all) is a disincentive to the import of a bunch of contact information into the program.
In addition, it would be nice if the merged contact "remembers" in some way the IDs of the contacts that were merged to form it, so I don't have to merge again the next time I import updated contacts from my phone to kaddressbook.
