I was looking at the database (through MySQLAdmin) to learn something, when i accidentally pressed a "T" button when viewing a table (comment_content). I think that altered something, as the MySQLAdmin interface replied this:
One index was added to comment_content (0 queries o.1038 seconds)
wp_comments ADD FULLTEXT (
Have i broken something? How can undo this? I am afraid this will bring doom in future upgrade to WP or something. And yes, i have a backup, but it is a little old, i will loose a lot of comments and a few posts if i restore it (i know, iknow...).
