I am not sure how the search engine works, but it needs to be reviewed. It may just be an issue with tagging the models correctly.
Some examples I found:
When searching "Washington", the Thomas Jefferson models do not show up
When searching "United States", the Thomas Jefferson models do not show up
When searching "Canada", Buffalo Crag and Famous Five Sisters show up, but Niagara Glen Bouldering does not
Feel free to experiment to try and understand how this works.
Edit some of the descriptions and titles and search for those terms, and see if you can find a pattern.
