[Grammar] I did manage to or I managed to

[Xinerub]

The topic says it all.

Which one is correct? Can I use both?

I did manage to find some evidence...
I managed to find some evidence...

Thanks a lot.

They're both acceptable. The first might be used if you wanted to emphasise your success in finding some evidence or to negate a suggestion that you did not find any evidence.
