Hello, Yutaka Emura Sung, You’re right. I have just tried Advanced Filter. It can does as my exception and is acceptable. However, if we can type AA BB or AA -BB, it will be more convenient.
For second requirements, I wanna say more. From myself, I like Emeditor very much and have a few experiences on Regular Expression. Almost everyday I use it to write or handle something. Therefore I often recommend it to my colleagues, my friends and my customers…….Some of them understand Regular Expression , but others feel crazy about it. We can’t assume all people are “computer expert” . A good software, should be not only powerful (has many many functions), but also as easier as possible. Then more and more people will like and use it.
For your reference.
