The search feature in “copy a post” is not working. I followed directions and searched by the exact title, but nothing comes up as a result. So I’m limited to copying only those posts that are in the box already. Too bad, because this is a nice feature I’ve used before
Try taking out part of the title when you do your search. That happens to me too (blank search results when I paste the entire title) so I just pick out 2-3 words from the title I want when I do a search. Does the trick!
The reference in the OP is to this feature > Copy a Post
Copy A Post lets you duplicate a post, including the title, contents, tags and categories, so you can start a new post without having to re-enter tags, categories and formatting.
Re: WordPress.com search missing posts
The search engine only indexes the body text of blog posts, pages, and comments. The blog name, post titles, and post/comment author names are not indexed.
