Lucene indexing

Lucene indexing is a process used by search engines to organize and store information from documents, making it quickly searchable. When a document is indexed, Lucene analyzes its content, breaks it down into terms (like words), and creates a structured representation that allows for fast retrieval. This process includes assigning relevance scores to different terms, ensuring that when you search for something, results are ranked by how closely they match your query. Essentially, Lucene helps turn vast amounts of text into a searchable format, enabling efficient information retrieval.
