findstr DOS Command's multiple string argument

How do I filter words "black" and "white"?

The following command will display all lines containing "black" NOR "white":

findstr /v "black white" blackwhite.txt

The following command will display all lines containing "black" OR "white":

findstr "black white" blackwhite.txt

The following command will display all lines containing EXACTLY "black white":

findstr /c:"black white" blackwhite.txt

The following command will display all lines containing "black" AND "white":

findstr "white" blackwhite.txt | findstr "black"

Notes:

• When the search string contains multiple words, separated with spaces, then findstr will return lines that contain either word (OR).

• A literal search (/C:string) will reverse this behaviour and allow searching for a phrase or sentence. A literal search also allow searching for punctuation characters.

Example data file (blackwhite.txt):

red
black
white
blue
black white
black and white

Example output:

F:\test>findstr /v "black white" blackwhite.txt

red
blue

F:\test>findstr "black white" blackwhite.txt
black
white
black white
black and white

F:\test>findstr /c:"black white" blackwhite.txt
black white

F:\test>findstr "white" blackwhite.txt | findstr "black"
black white
black and white
