如何查找同时包含两个查找字符的行

 

Finding two words in either orderEdit Finding two words in either order sectionEdit

 

You can search for a line that contains two words, in any order. For example, the following pattern finds all lines that contain both "red" and "blue", in any order:

 

.*red\&.*blue

 

In a pattern, \& separates alternates, each of which has to match at the same position. The two alternates in this example are:

 

    .*red (will match all characters from the beginning of a line to the end of the last "red"); and

    .*blue (will match all characters from the beginning of a line to the end of the last "blue"). 

 

A line which contains both "red" and "blue" will match both alternates, starting at the beginning of the line. The pattern .*red\&.*blue finds the last alternate (but only if all alternates match at the same position), so if you are highlighting matches, you will see text matched by .*blue highlighted.

 

An alternative procedure is to use a pattern that explicitly finds "red" followed by "blue", or "blue" followed by "red":

 

\(red.*blue\)\|\(blue.*red\)

 

To search for lines that contain only the whole words "red" and "blue", in either order, use one of the following patterns:

 

.*\<red\>\&.*\<blue\>

\(\<red\>.*\<blue\>\)\|\(\<blue\>.*\<red\>\)
