It's a scrapper for Bitcointalk only, yes. It's very well known if you are a regular forum user. I never use the forum's search function. Ninjastic.space is much better. You can search for terms in subjects or the body of the content. There are options to ignore topics and remove them from the final results, you can add a date range, and search in specific boards only. Even Google does a better job in my opinion than the forum search feature.
