Direct Hit Technologies: Direct Hit Technologies, Inc. was a Boston-based search engine company that provided search engine services to major web portals and operated a public search engine at directhit.com.  Founded in April 1998 by Gary Culliss and Mike Cassidy, the Direct Hit search engine utilized the anonymous searching activity of millions of web searchers to rank web sites based on a number of patented algorithms, such as how long searchers spent viewing each web page and where a site was ranked in the original search results list.

Bilingual search engine: A bilingual search engine provides multiple language search pages when users type keyword in one language.  Obviously, this kind of search engine will give more detailed information for people who speak more than one language, although many mainstream search engines provide multiple languages services.  However, the difference between a bilingual search engine and a multiple language search engine is a bilingual search engine will translate keyword from one language to another automatically.  Google also published a plug-in (Bilingual Search Suggestion) for Chrome browser to meet the requirement of bilingual search,but it was canceled and unable be found in Chrome web store now.

Search analytics: Search analytics is the use of search data to investigate particular interactions among Web searchers, the search engine, or the content during searching episodes.  The resulting analysis and aggregation of search engine statistics can be used in search engine marketing (SEM) and search engine optimization (SEO).  In other words, search analytics helps website owners understand and improve their performance on search engines, for example identifying highly valuable site visitors, or understanding user intent.  Search analytics includes search volume trends and analysis, reverse searching (entering websites to see their keywords), keyword monitoring, search result and advertisement history, advertisement spending statistics, website comparisons, affiliate marketing statistics, multivariate ad testing, et al.

Local search engine optimisation: Local search engine optimization (SEO) is similar to (national) SEO in that it is also a process affecting the visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results.  In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers.  Local SEO however differs in that it is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when users enter local searches for its products or services.  Ranking for local search requires a similar process to general SEO but has some specific elements to rank a business for local search.

Rollyo: Rollyo was a Yahoo!-powered search engine which allowed users to register accounts and create personalized search engines.  Each search engine could include up to 25 websites/blogs chosen by the user.  Search results were limited to the sites included in a particular search engine.  Additionally, users could share their "rolled" engines with other contributors or post a mini search box to the user's website using HTML.  It was also possible to add each "searchroll" to the Mozilla Firefox search bar and to make Rollyo the default search engine for Firefox.

YossarianLives: Yossarian Lives is a metaphorical search engine, a type of Internet search engine.  Its algorithms return results that are disparate, but potentially metaphorically related to the user's query.  These results are intended to encourage creative thinking and diversity of thought.  "We don't want you to know what everyone else knows, we want you to generate new knowledge."  The search engine emphasizes new knowledge vs. the reinforcing of existing information.  The site works to avoid the "filter bubble" by returning results that are conceptually related but disparate, compared with traditional search engines that return the most popular or common results.

Search engine optimization: Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results.  In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers.  SEO may target different kinds of search, including image search, video search, academic search, news search, and industry-specific vertical search engines.  SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services.  The former instead is more focused on national or international searches.

DuckDuckGo: DuckDuckGo (DDG) is an Internet search engine that emphasizes protecting searchers' privacy and avoiding the filter bubble of personalized search results.  DuckDuckGo distinguishes itself from other search engines by not profiling its users and by deliberately showing all users the same search results for a given search term.  DuckDuckGo emphasizes returning the best results, rather than the most results, and generates those results from over 400 individual sources, including key crowdsourced sites such as Wikipedia, and other search engines like Bing, Yahoo!, Yandex, and Yummly.
