The three dominant English search engines with their own indexes[^1] are Google, Bing, and Yandex (GBY). Many alternatives to GBY exist, but almost none of them have their own results; instead, they just source their results from GBY. With that in mind, I decided to test and catalog all the different indexing search engines I could find. I prioritized breadth over depth, and encourage readers to try the engines out themselves if they'd like more information. I primarily evaluated English-speaking search engines because that's my primary language. With some difficulty, I could probably evaluate a Spanish one; however, I wasn't able to find many Spanish-language engines powered by their own crawlers. This page is a "living document" that I plan on updating indefinitely. Check for updates once in a while if you find this page interesting. Feel free to send me suggestions, updates, and corrections; I'd especially appreciate help from those who speak languages besides English and can evaluate a non-English indexing search engine. Contact info is in the article footer. Methodology ----------- I mainly evaluated link results, and didn't focus too much on (often glaring) privacy issues, "enhanced" or "instant" results (e.g. Wikipedia sidebars, related searches, Stack Exchange answers), or other elements. I compared results for esoteric queries side-by-side; if the first 20 results were (nearly) identical to another engine's results (though perhaps in a slightly different order), they were likely sourced externally and not from an independent index. I tried to pick queries that should have a good number of results and show variance between search engines. An incomplete selection of queries I tested: - "vim", "emacs", "neovim", and "nvimrc": Search engines with relevant results for "nvimrc" typically have a big index. Finding relevant results for the text editors "vim" and "emacs" instead of other topics that share the name is a challenging task. - "vim cleaner": should return results related to a [line of cleaning products](https://en.wikipedia.org/wiki/Vim_%28cleaning_product%29) rather than the Correct Text Editor. - "Seirdy": My site is relatively low-traffic, but my nickname is pretty unique and visible on several of the highest-traffic sites out there. - "Project London": a small movie made with volunteers and FLOSS without much advertising. If links related to the movie show up, the engine's really good. - "oppenheimer": a name that could refer to many things. Without context, it should refer to the physicist who worked on the atomic bomb in Los Alamos. Other historical queries: "magna carta" (intermediate), "the prince" (very hard). General indexing search-engines ------------------------------- ### Large indexes, good results These are large engines that pass all the above tests and more. - Google: the biggest index. Allows submitting pages and sitemaps for crawling, but requires login. Powers a few other engines: - Startpage - Runnaroo - SAPO (Portuguese interface, can work with English results) - Bing: the runner-up. Allows submitting pages and sitemaps for crawling, but requires login. Its index powers many other engines: - Yahoo - DuckDuckGo[^2] - AOL - Qwant[^3] - Ecosia - Ekoru - Privado - Findx - Disconnect Search[^4] - PrivacyWall - Lilo - SearchScene - Peekier - Oscobo - Million Short - Yippy search[^5] - Lycos - Givero - Swisscows - Ask.moe[^6] - Partially powers MetaGer by default; this can be turned off - At this point, I stopped adding Bing-based search engines. There are just too many. - Yandex: originally a Russian search engine, it now has an English version. Some Russian results bleed into its English site. Allows submitting pages and sitemaps for crawling, but requires login. Powers: - Epic Search - Occasionally powers DuckDuckGo's link results instead of Bing. - Mojeek: Claims to be privacy-oriented. Quality isn't at Google/Bing/Yandex's level, but it's not bad either. If I had to use Mojeek as my default general search engine, I'd live. - Petal search: [gopetal.com](https://www.gopetal.com/) and [petalsearch.com](https://petalsearch.com/). A very new engine developed by Huawei. Surprisingly good results; it passed all the listed tests. Requires an account to submit sites. I discovered this via my access logs. ### Smaller indexes, relevant results These engines pass most of the tests listed in the "methodology" section. - [Right Dao](https://rightdao.com): very fast, good results. Passes the tests fairly well. - [Gigablast](https://gigablast.com/): It's been around for a while and also sports a classic web directory. Searches are a bit slow, and it charges to submit sites for crawling. It powers [Private.sh](https://private.sh). Gigablast is tied with Right Dao for quality. - [Gowiki](https://gowiki.com): Very young, small index, but shows promise. I discovered this in the seirdy.one access logs. Currently only available in the US. ### Smaller indexes, hit-and-miss These engines fail badly at a few important tests. - [seekport](http://www.seekport.com/): The interface is in German but it supports searching in English just fine. The default language is selected by your locale. It's really good considering its small index; it hasn't heard of less common terms (e.g. "Seirdy"), but it's able to find relevant results in other tests. - [Exalead](https://www.exalead.com/search/): slow, quality is hit-and-miss. Its indexer claims to crawl the DMOZ directory, which has since shut down and been replaced by the [Curlie](https://curlie.org) directory. No relevant results for "Oppenheimer" and some other history-related queries. Allows submitting individual URLs for indexing, but requires solving a Google reCAPTCHA and entering an email address. - [wbsrch](https://wbsrch.com/): In addition to its generalist search, it also has many other utilities related to domain name statistics. Failed multiple tests. Its index is a bit dated; it has an old backlog of sites it hasn't finished indexing. It also has several per-language indexes. - [ExactSeek](https://www.exactseek.com/): small index, disproportionately dominated by big sites. Failed multiple tests. Allows submitting individual URLs for crawling, but requires entering an email address and receiving a newsletter. Webmaster tools seem to heavily push for paid SEO options. - [Meorca](https://meorca.com/): a search engine that claims not to "index pornography or illegal content websites". It also features a public blog with a marketplace and free games. Allows submitting URLs, but requires a full name, email, phone number, and "business name" to do so. Discovered in the seirdy.one access logs. - [search.tl](http://www.search.tl/): Generalist search for one TLD at a time (defaults to .com). I'm not sure why you'd want to always limit your searches to a single TLD, but now you can.[^7] There isn't any visible UI for changing the TLD for available results; you need to add/change the `tld` URL parameter. For example, to search .org sites, append `&tld=org` to the URL. It seems to be connected to [Amidalla](http://www.amidalla.de/), but Amidalla doesn't seem to currently be operational. Amidalla allows users to manually add URLs to its index and directory; I have yet to see if doing so impacts search.tl results. ### Unusable engines, irrelevant results Results from these search engines don't seem at all useful. - YaCy: community-made index; slow. Results are awful/irrelevant, but can be useful for intranet or custom search. - Scopia: only seems to be available via the [MetaGer](https://metager.org) metasearch engine after turning off Bing and news results. Tiny index, very low-quality. - [Active Search Results](https://www.activesearchresults.com): very poor quality - Crawlson: young, slow. In this category because its index has a cap of 10 URLs per domain. I initially discovered Crawlson in the seirdy.one access logs. The site seems to be down right now, so I didn't link it. - [Anoox](https://www.anoox.com/): Results are few and irrelevant; fails to find any results for basic terms. Allows site submission. It's also a lightweight social network and claims to be powered by its users, letting members vote on listings to alter rankings. - [Plumb](https://plumb.one/): Almost all queries return no results; when this happens, it loads Google's Custom Search scripts from `cse.google.com` onto the page to do a client-side Google search. This can be mitigated by using a browser addon to block `cse.google.com` from loading any scripts. Plumb claims that this is a temporary measure while its index grows. Allows submitting URLs, but requires solving an hCaptcha; as of 2021-03-19, the hCaptcha is broken (missing sitekey). This engine is very new; hopefully as it improves, it could graduate from this section. Its Chief Product Officer [previously founded](https://archive.is/oVAre) the Gibiru search engine which shares the same affiliates. Non-generalist search --------------------- These indexing search engines don't have a Google-like "ask me anything" endgame; they're trying to do something different. - Wiby: [wiby.me](https://wiby.me) and [wiby.org](https://wiby.org): I love this one. It focuses on smaller independent sites that capture the spirit of the "early" web. It's more focused on "discovering" new interesting pages that match a set of keywords than finding a specific resources. I like to think of Wiby as an engine for surfing, not searching. Runnaroo occasionally features a hit from Wiby. If you have a small site or blog that isn't very "commercial", consider submitting it to the index. - [Search My Site](https://searchmysite.net): Similar to Wiby, but only indexes user-submitted personal and independent sites. It optionally supports IndieAuth. - [Quor](https://www.quor.com): seems to mainly index large news sites. Other languages --------------- I'm unable to evaluate these engines properly since I don't speak the necessary languages. English searches on these are a hit-or-miss. I might have made a few mistakes in this category. ### Big indexes - Baidu: Chinese - Qihoo 360: Chinese. I'm not sure how independent this one is. - Sogou: Chinese - Yisou: Chinese - [Naver](https://search.naver.com): Korean. - [Seznam](https://www.seznam.cz/): Czech, seems relatively privacy-friendly. Discovered in the seirdy.one access logs. - [Cốc Cốc](https://coccoc.com/search): Vietnamese ### Smaller indexes - [Parsijoo](https://www.parsijoo.ir/): Persian - [search.ch](https://search.ch): Regional search engine for Switzerland; users can restrict searches to their local regions. - [fastbot](https://www.fastbot.de/): German - [Moose.at](https://www.moose.at): German (Austria-based) Misc ---- - Ask.com: the main site shut down, but subdomains like [uk.ask.com](https://uk.ask.com) are still alive. They claim to outsource search results. The results seem similar to Google, Bing, and Yandex; however, I can't pinpoint exactly where their results are coming from. - 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. Upcoming engines ---------------- These engines aren't ready yet; their indexes are either in a proof-of-concept phase with a handful of sites, or aren't available yet. - Apple: given the activity of the AppleBot crawler lately, their index will almost certainly grow to a size large enough to power a general search engine soon. Check your server's access logs; there's a good chance it's crawled your site if you have a few backlinks. - Brave [announced](https://brave.com/search/) that it will start its own independent search engine based on the now-discontinued Cliqz. I don't endorse the company, but I hope its results will be available through metasearch engines like Searx. Acknowledgements ---------------- Some of this content came from the [Search Engine Map](https://www.searchenginemap.com/) and [Search Engine Party](https://searchengine.party/). A few web directories also proved useful. [^1]: Yes, "indexes" is an acceptable plural form of the word "index". The word "indices" sounds weird to me outside a math class. [^2]: DuckDuckGo has a crawler called DuckDuckBot. This crawler doesn't impact the linked results displayed; it just grabs favicons and scrapes data for a few instant answers [^3]: Qwant claims to also use its own crawler for results, but it's still mostly Bing. Try a side-by-side comparison; I found that it doesn't seem to have anything besides Bing results. [^4]: Disconnect Search allows users to have results proxied from Bing or Yahoo, but Yahoo sources its results from Bing. [^5]: Yippy claims to be powered by a certain IBM brand (a brand that could correspond to any number of products) and annotates results with the phrase "Yippy Index", but a side-by-side comparison with Bing and other Bing-based engines revealed results to be nearly identical. [^6]: Ask.moe was working on a [FLOSS indexer](https://git.sr.ht/~danskeren/spider.moe); its search page stated an intention to switch to it from Bing at one point. This statement has since been removed. [^7]: Google and Bing support the `site:` search operator to limit searches to subpages/subdomains of a single site, but it can also limit searches to a single TLD. `site:.one`, for instance, limits searches to websites with the ".one" TLD.
