How filter post WP Blog By TAG

In the wordpress blog we can show only some posted by category with "query_posts('cat=3')" code in the loop. For my case, I want filter to show posted like that, but not by category. I want filter by TAGs, How do that?

 

Try this plugin...I think it does what you want to do. Just give it the name of the tag and it will list the most recent articles with that tag.

Its quite easy if you know how to modify your theme:

[I]query_posts[/I]('[I]tag[/I]=cooking');

Code (markup):

Or if you want to just grab posts that have 2 or more tags on them

[I]query_posts[/I]('[I]tag[/I]=cooking+pie+soup');

Code (markup):

Good Luck

 

Thanks ThePhoenixBird, I need like that.
