vim搜索 不区分大小写
By default, Vim/Vi’s search is case sensitive. However, if I want to search case insensitively, is there any method?
默认情况下 ，Vim / Vi的搜索区分大小写。 但是，如果我不区分大小写地搜索，有什么方法吗？
For example, I search fordot, instead ofdog, I also want to find out phases containingDog,DOg, etc.
例如，我搜索dot而不是dog，我还想找出包含Dog，DOg等的阶段。
There are several methods:
有几种方法：
1. Setting the search to be case insensitive in Vim
1.在Vim中将搜索设置为不区分大小写
:set ignorecase
To unset it:
要取消设置：
:set noignorecase
You can also put it to your .vimrc if you want the behavior to be the default one.
如果您希望将行为设为默认行为，也可以将其放入.vimrc。
2. You can also force a patten to be case insensitive or sensitive bycorCregardless the setting ofignorecase.
2.您也可以强制patten不区分大小写，或者由c或C强制区分大小写，无论ignorecase的设置如何。
For example, the search/dogcis always case insensitive. And/dog/Cis always case sensitive.
例如，搜索/dogc始终不区分大小写。 并且/dog/C始终区分大小写。
3. Usesmartcase
3.使用smartcase
To enable it:
要启用它：
:set smartcase
If your search pattern is purely lowercase, it will search case insensitively.
If your search pattern contains uppercase characters, it will search case sensitively.
如果您的搜索模式是完全小写的，它将不区分大小写地搜索。
如果您的搜索模式包含大写字符，它将区分大小写。
