I could have sworn I replied days again…
I can not replicate the problem, my social media test CVS still imports without any problems. Can you attach a sample of the CSV that is causing you the problem?
The search is keyword search much like WP itself. WP sorts by post date [if I remember correctly, that is], Connections sorts by name. But to answer your question, every couple releases I tweak to make it better. If your db setup supports it and you don’t mind making a very small edit to a PHP file, I can give you instructions that’ll yield much better relevant results, but still sorted by name.
