It is a limitation of the current implementation of the ghosthunter plugin, but currently only the latest 15 posts will be searched.
The version of ghosthunter we're using uses the RSS feed as it's source, which according to this post is hard coded to 15 posts.
It looks like the latest version uses the public ghost API, but that does require you enable it, and looks like it may have some performance issues at present.
I suggest we keep an eye on the project for now till it looks like a good option 😄
