Today, all the facts are stored as strings, and therefore integer comparison doesn't work on them.
There should be a way to handle different types (integer, floats etc).

In order to avoid hard coding either in the database or the code, I was thinking about using ext_method in app/models/concerns/hostext/search.rb which will either guess the type from the value, or use a setting and will then use CAST to perform the right comparison.
