Introduction to search engines
Search engine is one of the most important components of Internet technology. It is used to collect, organize, index and store massive data. Its main function is to quickly retrieve, sort and filter massive documents to provide users with a good retrieval experience. At present, search engines have become a part of online life, such as Google, Baidu, Bing, Yahoo, etc. Search engines can help users quickly find the information they need and reduce the waste of time and energy. Search engines have greatly improved the quality of Internet services by improving retrieval efficiency and relevance.
Traditional search engine systems are implemented based on stand-alone hardware. With the development of information technology, the requirements are becoming more and more complex, the number of users is increasing, and the requirements for system performance are also getting higher and higher. In order to cope with this challenge, search engine technology researchers have turned their attention to distributed computing and NoSQL technology, and developed search engines for cloud computing environments. This article will explore how to write an open source search engine project-Tantivy in Rust language.
What is Tantivy?
Tantivy is a new open source search engine project created by Mozilla Research. It is a search engine library written purely in Rust language and supports multiple programming languages such as Python, JavaScript and Java. The goal of Tantivy is to maintain good performance while processing massive amounts of data in memory. It can quickly index and search large-scale text data sets, and can be used to build lightweight web search engines or desktop search applications. Tantivy supports simple query syntax and has very high query performance. Tantivy provides a simple and easy-to-use API, making it very easy to learn and use.
Why choose Rust language?
The Rust language has outstanding performance in speed, memory safety, thread safety and concurrency. As an efficient, zero
