I asked WordPress support about the search function failing to
find either my blog, my user name, or headings and topics I’ve actually published.
The WordPress.com search engine indexes post, pages, and comments content (body text).
Unless entered as text in those contents, blog name, post titles, and post/comment author names are not indexed.
For full details on the engine, please see:
Hence, from now on I will be including such details in the text body of my posts.
Just thought this might be of interest to fellow bloggers 🙂
