The Emacs occur buffer is editable, but it does not make it easy to delete lines. One normally gets something like this:
2 matches for "Wyk" in buffer: diary 59:%%(diary-anniversary 5 15 2014) Nicholas Wyk 61:%% van Wyk To delete the above lines one has to position one's cursor after each line number and invoke C-k. The line numbers themselves are given the read-only text property, so even if the buffer is made read-write, C-k will refuse to delete the line if the cursor is before the line number. It would be easier if line numbers were not shown.
Is there a better way?
