Search engine (computing)System to help searching for information In computing, a search engine is an information retrieval software system designed to help find information stored on one or more computer systems. Search engines discover, crawl, transform, and store information for retrieval and presentation in response to user queries. The search results are usually presented in a list and are commonly called hits.
Doug CuttingDouglass Read Cutting is a software designer, advocate for, and creator of open-source search technology. He founded two technology projects, Lucene and Nutch, with Mike Cafarella. The Apache Software Foundation now manages both projects. Cutting and Cafarella were also co-founders of Apache Hadoop. Education and early careerCutting graduated from Stanford University in 1985 with a bachelor's degree.
The Apache Software FoundationThe Apache Software Foundation ( ; ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) that supports a number of open-source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers.
Java (programming language)Object-oriented programming languageJava is a high-level, general-purpose, memory-safe, object-orientedprogramming language. It is intended to let programmerswrite once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are usually compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.
Free and open-source softwareFreely licensed software with open codeScreenshot of free and open-source software: Debian running KDE Plasma, Firefox, Dolphin, VLC, LibreOffice Writer, GIMP, and KCalcFree and open-source software (FOSS) is software available under a license that gives users the right to use, share, modify, and distribute the software — modified or not — to everyone and provides the means to exercise those rights using the software's source code.Apache LicenseThe Apache License is a permissive free-software and free and open source software license written by the Apache Software Foundation (ASF). It allows users to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software under the terms of the license, without concern for royalties. The ASF and its projects release their software products under the Apache License. The license is also used by many non-ASF projects.
C++General-purpose programming languageC++ is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup. First released in 1985 as an extension of the C programming language, adding object-oriented (OOP) functionality and later expanding significantly with the addition of functional programming features.
Object PascalObject Pascal is an extension to the programming language Pascal that provides object-oriented programming (OOP) features such as classes and methods. The language was originally developed by Apple Computer as Clascal for the Lisa Workshop development system. As Lisa gave way to Macintosh, Apple collaborated with Niklaus Wirth, the author of Pascal, to develop an officially standardized version of Clascal. This was renamed Object Pascal.
Library (computing)In computing, a library is a collection of resources that can be used during software development to implement a computer program. Commonly, a library consists of executable code such as compiledfunctions and classes, or a library can be a collection of source code. A resource library may contain data such as images and text. A library can be used by multiple, independent consumers (programs and other libraries).
Python (programming language)General-purpose programming languagePython is a high-level, general-purpose programming language that emphasizes code readability, simplicity, and ease-of-writing with the use of significant indentation, an extensive ("batteries-included") standard library, and garbage collection. Python supports multiple programming paradigms but with an emphasis on object-oriented programming and dynamic typing.
PerlInterpreted programming language first released in 1987Perl is a high-level, general-purpose, interpreted, dynamic programming language. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unixscripting language to make report processing easier. Since then, it has undergone many changes and revisions.
C Sharp (programming language)General-purpose programming languageC# ( ) is a general-purposehigh-levelprogramming language supporting multiple paradigms. C# encompasses static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. The principal designers of the C# programming language were Anders Hejlsberg, Scott Wiltamuth, and Peter Golde from Microsoft.*As an Amazon Associate I earn from qualifying purchases.
