First do
(occur "string1" nil)
Then switch to the *Occur* buffer and do
(occur "string2" nil)
result:
0 lines matching "string2" in buffer *Occur*.
Why of course. It will never find string2 because it first clears
that buffer for putting the result into, the reader says to himself
laughing. However: 1. it doesn't warn about this in the docs nor does
the program stop you from doing this.
2. saying '0 lines matching "string2" in buffer *Occur*' isn't the
best thing to say, as there were clearly plenty of string2 before all
was wiped away. 3. why don't you not make this a special case and
give the user what he wants, with even an undo enabled to restore
previous states of the *Occur* buffer. [No I am not planning on asking
you to make also grep string file > file work in the shell.]
