An analyzer is composed of a tokenizer and a series of filters. Lucene provides several built-in analyzers, each tailored to handle specific languages or use cases. Analyzers, Tokenizers, and FiltersĪnalyzers are responsible for processing input text and breaking it down into a series of tokens. The structure of a document is defined by the developer, allowing for a flexible schema that can adapt to varying data models. A Document is a container for a set of Field objects, where each Field represents a named piece of data with a specific type and value. In Lucene, data is represented as a collection of Document objects. Understanding the Core Components of Apache Lucene 1.
