searchable forum

[Randy5]

When you add a forum to your website, how do you make it searchable? Or is this a common feature with most forums you can get?

vBulletin
In a new installation, there is only one type of search installed. This is called "DB Search" and is an indexed implementation of Fulltext Search allowing you to search all content types marked as "Searchable" when they are created/installed in your system.
You can find alternative search engines from third-party vendors or possibly at vBulletin.org Forum - The Official vBulletin Resource!

phpBB
on the Search settings page, you can control what search backend your board's search functionality will use for indexing posts and searching, and set various options related to it. There are four main categories of search settings: General Search Settings, Search Backend, Fulltext mysql, and Fulltext native.
