I've imported all the threads and posts from my previous SMF installation, and everything works fine, except that the forum search function does not find anything from those imported threads/posts. Neither thread title nor post content can be found.
Can this be fixed, or is it something I just have to live with?
Finalizing the Import
A required action once the import is complete is to rebuild the search index. Failure to do so will make it impossible for searches to be performed on the imported data. To rebuild it, click on the Tools tab and then the Rebuild Caches icon. Depending on the number of posts and quantity of data, this could take a long time.
