FAQ Or Wiki Feature

[appsteve]

Hi guys. So, I've setup my site using Publii and I really like Publii and how it works. However, I'd like to setup a FAQ or Wiki like page on my site. Is this possible? I'm thinking if there is possible code or plugin that allows entering information into a flat file, and then a search feature to be able to search that flat file based on key words to load and show the entries. Is this possible or is there an existing plugin or code to implement this?
Thanks
