Chapter 3 Searching

Simple Searches

I remember i used to use a stupid ':' before '/' , now I know that only '/' is enough!

find a string: /string<ENTER>

*[]^%//?~$ have special meaning, so if you want to  use them in a search you must put a backslash / in front of them

find a . : //.

to find the next matching, you can use either /<Enter> or n   3/ and 3n are also correct

Make full use of search history

input a /, then use <Up> key, u will find search history

Searching options

Highlighting

:set hlsearch

:set nohlsearch

只是把当前搜到的结果去除Highlighting的方法是 :nohlsearch

Incremental searches

:set incsearch

:set noincsearch

Searching Backward

use ? instead of /

? and n to find next matching backward        3? and 3n are also correct

Changing Direction

reverse the direction: N  (注意一个小点，就在第一次会转向，然后就和n一样了；就是说第一次使用N的时候会转向)

always backward: ?

always forward: /

always the same direction: n

Basic Regular Expressions: extremely powerful and compact way to specify a search pattern

start of line: ^

end of line: $

a single charater: .

x: any literal charater x

/charater: turns off the special  meaning of many charaters

Example:

/^the

/the$

/^the$:  means only 'the' appears in the line, spaces cannot appear either in front of 'the' or after 'the'

/^$: search for empty line

生单词一枚coincidence [koˈɪnsɪdəns]n. 1. （令人吃惊的）巧合，巧事2. （意见等的）相同, 符合, 一致3. 同时存在；并存

Example: It is no coincidence that this is also the command to move to the beginning of the line.

我觉得这句话的意思就是说：并不是巧合。。。意味着是必然
