I've been exploring intelx.io, which boasts an impressive 224 billion records and can deliver search results in mere seconds. In contrast, I've been experimenting with my setup using ClickHouse with about 3 billion rows, but my queries take 5-10 minutes to return results. How can intelx.io and similar services like infotrail.io optimize their performance? Is it primarily due to powerful servers, or is there more to it?

The key to those fast searches often lies in techniques like creating inverted indexes and utilizing sharding. Instead of searching through each record for terms like "white dogs", they make lists of documents that contain each word, leveraging binary searches for super quick lookups. It's about optimizing the search process, not just having strong servers.
Good performance often hinges on a combination of caching, horizontal scaling, and smart data partitioning. Those technologies can significantly reduce query times, even with huge amounts of data.
It's not only about beefy servers. Sure, strong servers play a role, but the real secret sauce could be a mix of effective indexing, caching, and partitioning strategies that work together to enhance performance.
Indexing is definitely important! If you haven’t set up proper indexing on your data, you might be missing out on some serious speed boosts. Also, remember that using clever architecture can help as well.
I would bet it comes down to robust indexing and possibly top-tier caching strategies. For massive datasets, systems like Elasticsearch can perform really well. It's not just about how big the server is, but how the data is organized and accessed.
