Java Search Engine Libraries are used to make search engines for specific applications. It is the most popular language in the world, and it is also a platform for many other applications. The search engine libraries have been designed to provide quality results and fast response times. A Java search engine library is a collection of algorithms that allows you to quickly and easily create your own custom-built searches. These libraries are designed to allow programmers who do not have extensive knowledge of computer science to implement their own searches. Elasticsearch is a distributed RESTful search engine capable of solving many use cases encountered when searching large volumes of data held in an elasticsearch cluster. It combines the scalability and flexibility of NoSQL with the power of search so you can make sense of your data. OpenSearch provides an abstraction layer for a number of search APIs including Google, Bing, Yahoo and Yandex. It allows you to easily write your own implementation of a search engine and plug it into your application by just adding a few lines of code. The macrobase library was created by the Google Search team, which means that it's well tested and very stable. This library allows you to build scalable search engines without having to worry about the details of indexing, searching and ranking results. Full list of the best open source Java Search Engine Libraries are below.
