I wouldn’t want to create a category and edit all posts to be in that category… I have thousands of posts.
1) Try to search for a keyword from your wordpress search box.
2) Take note of the URL
I just would that search result content are used to create a post.
Example:
1) I search for “blue widget” and obtain all posts related to “blue widget”
2) URL is /index.php?s=blue+widget
3) I would like to (semi)automatically create a post that will list those identical result.
I hope to explain myself well.
Thanks for interesting.
