I am creating a vocabulary site. Each post contains one word in the title. I will eventually have hundreds of words in multiple categories (e.g., "10H 1" and "11AP 2"). When a word is entered, it is filed in only one category. It is possible that the same word may be added in the future, but in a different category.
I would like to be able to have an easy way to find duplicate words so I can combine the posts and file each under multiple categories.
The permalink slug is only the word. I know that if I duplicate a word in separate posts, the second plug will be "word-2". How do I search for plugs that contain "-2" so that I can combine the two posts?
(I have already tried using the search box on the Manage Posts page and it does not find "-2" slugs.)
