The English Wikipedia is the English-language edition of the free online encyclopedia Wikipedia. Founded on 15 January 2001, it is the first edition of Wikipedia and, as of November 2020, has the most articles of any edition. As of November 2020, 11% of articles in all Wikipedias belong to the English-language edition. This share has gradually declined from more than 50 percent in 2003, due to the growth of Wikipedias in other languages. As of 5 November 2020, there are 6,185,132 articles on the site, having surpassed the 6 million mark on 23 January 2020. In August 2019, the total volume of the compressed texts of the English Wikipedia's articles amounted to 16.1 gigabytes.

Findability is the ease with which information contained on a website can be found, both from outside the website and by users already on the website. Although findability has relevance outside the World Wide Web, the term is usually used in that context. Most relevant websites do not come up in the top results because designers and engineers do not cater to the way ranking algorithms work currently. Its importance can be determined from the first law of e-commerce, which states "If the user can’t find the product, the user can’t buy the product." As of December 2014, out of 10.3 billion monthly Google searches by Internet users in the United States, an estimated 78% are made to research products and services online.
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index that reflects the yearly average number of citations that articles published in the last two years in a given journal received.

Citation impact is a measure of how many times an academic journal article or book or author is cited by other articles, books or authors. Citation counts are interpreted as measures of the impact or influence of academic work and have given rise to the field of bibliometrics or scientometrics, specializing in the study of patterns of academic impact through citation analysis. The journal impact factor, the two-year average ratio of citations to articles published, is a measure of the importance of journals. It is used by academic institutions in decisions about academic tenure, promotion and hiring, and hence also used by authors in deciding which journal to publish in. Citation-like measures are also used in other fields that do ranking, such as Google's PageRank algorithm, software metrics, college and university rankings, and business performance indicators.

A search engine is a software system that is designed to carry out web searches, which means to search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Internet content that is not capable of being searched by a web search engine is generally described as the deep web.
The Uzbek Wikipedia is the Uzbek-language edition of the free online encyclopedia Wikipedia. It was founded in December 2003. Articles in the Uzbek-language edition are written in the Latin script.

A WikiProject, or Wikiproject, is the organization of a group of participants in a wiki established in order to achieve specific editing goals, or to achieve goals relating to a specific field of knowledge. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. Unrelated wikis have also used the term, for example OpenStreetMap. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by Smithsonian Magazine for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".
