* Kozmonavt: Has a small index of almost 5 million sites. If I want to find the website for a certain project, Kozmonavt works well (provided its index has crawled said website). It works poorly for learning things and finding general information. I cannot recommend it for anything serious since it lacks contact information, a privacy policy, or any other information about the org/people who made it. Discovered in the seirdy.one access logs.
* Burf.co: Very small index, but seems fine at ranking more relevant results higher. Allows site submission without any extra steps.
* Entfer: a newcomer that lets registered users upvote/downvote search results to customize ranking. Doesn't offer much information on who made it. Its index is small, but it does seem to return results related to the query.
* Siik: Lacks contact info, and the ToS and Privacy Policy links are dead. Seems to have PHP errors in the backend for some of its instant-answer widgets. If you scroll past all that, it does have web results powered by what seems to be its own index. These results do tend to be somewhat relevant, but the index seems too small for more specific queries.

* Secret Search Engine Labs: Very small index with very little SEO spam; it toes the line between a "search engine" and a "surf engine". It's best for reading about broad topics that would otherwise be dominated by SEO spam, thanks to its CashRank algorithm. Allows site submission.

* Ask.com: The site is back. They claim to outsource search results. The results seem similar to Google, Bing, and Yandex; however, I cant pinpoint exactly where their results are coming from. Also, several sites from the "ask.com network" such as directhit.com, info.com, and kensaq.com have uniqe-looking results.
- Not evaluated: Apple's search. It's only accessible through a search widget in iOS and macOS and shows very few results. This might change; see the next section.
- Partially evaluated: [Infinity Search](https://infinitysearch.co): young, small index. It recently split into a paid offering with the main index and [Infinity Decentralized](https://infinitydecentralized.com/), the latter of which allows users to select from community-hosted crawlers. I managed to try it out before it became a paid offering, and it seemed decent; however, I wasn't able to run the tests listed in the "Methodology" section. Allows submitting URLs and sitemaps into a text box, no other work required.
