problems

1. I open deft and search elisp , then press RET, deft will open the file A , and put cursor at elisp
2. Then I go back to deft buffer，and search emacs which also in file A (file A buffer not kill), deft will still open file A,
   but cursor still put at elisp, what i expect it should put cursor at emacs

If I kill buffer file A and search again with emacs, it can put cursor at emacs

Should I need to set any variable to make it work ? Or I need to kill buffer every time before I exec deft?
