2/27/2023 0 Comments Apache lucene 2 downloadAs of now, Lucene 6, the Lucene distribution contains approximately two dozen package-specific jars, these cuts down on the size of an application at a small cost to the complexity of the build file. The Lucene API consists of a core library and many contributed libraries. Lucene has a highly expressive search API that takes a search query and returns a set of documents ranked by relevancy with documents most similar to the query having the highest score. Lucene provides many ways to break a piece of text into tokens as well as hooks that allow you to write custom tokenizers. There are two ways to store text data: string fields store the entire item as one string text fields store the data as a series of tokens. Fields are constrained to store only one kind of data, either binary, numeric, or text data. Lucene does not in any way constrain document structures. A field consists of a field name that is a string and one or more field values. Lucene provides search over documents where a document is essentially a collection of fields. Therefore, it’s popular in both academic and commercial settings due to its performance, reconfigurability, and generous licensing terms. Most importantly, it is a cross-platform solution. It utilizes powerful, accurate and efficient search algorithms written in Java. Lucene offers powerful features like scalable and high-performance indexing of the documents and search capability through a simple API. The 2022 Trend Report on Kubernetes in the Enterprise. A step-by-step example of documents indexing and searching will be shown too. In this article, we will see some exciting features of Apache Lucene. It is a technology suitable for nearly any application that requires full-text search, especially in a cross-platform environment. Apache Lucene is a high-performance and full-featured text search engine library written entirely in Java from the Apache Software Foundation.
