cut whole lines and paste them to a new file?

Hi,

first I want to say that EmEditor is a great tool.
There is one question I want to ask.

Is there a way to cut whole lines that contain a specified phrase and paste them to a new file?

Let me explain a bit. For example there is a file that contains the following lines:

test-AB-test
test-AA-test
test-AA1-test
test-AC-test
test-AA2-test
test-AD-test

I search for “AA” and EmEditor cut these lines and generates a new file with the lines:

test-AA-test
test-AA1-test
test-AA2-test

The original file now contains only these lines without “AA”:

test-AB-test
test-AC-test
test-AD-test

The new generated file with the “AA”-lines can be saved with a new name.

I tried several ways with “regular expressions” or “search and replace” but I couldn´t find out how the whole lines are cut out of the original file.

Any help available?
Thanks a lot in advance for support.
