I'd highly recommend Solr[0] for searching to cut down the load. Or, if this is a static site, you could use Lunr[1] to have an efficient search that runs on the client. Is this site OSS?
Thank you. I will check out Solr. I'm using Elasticsearch currently for the readmes, but I disabled it while troubleshooting so it's currently just searching on titles and descriptions via mysql. I will re-enable elasticsearch later and figure out how to better optimize it for future traffic.
That's not what people use the term "self-hosted" for. It doesn't really apply to websites that you created yourself. It rather applies to off-the-shelf software that you use as an alternative to SaaS offerings.
Perhaps we need a new term or two to distinguish between "services I provide through providers" and "services I provide with my own metal" (except ISP and power, 'cause I run my services but I'm not buying a power plant).
At the moment people, myself included, use "self-host" for both.
Most of the "HN crowd" like cloudflare a lot, as it's quite convenient, especially for personal projects. There are a few very vocal people who dislike it for all kinds of reasons: taking down too much, not taking down enough, centralization, etc.
