Apache LuceneTM is a high-performance, full-featured text search engine library written entirely in Java. In addition to the standard FullText Index, which uses the SB-Tree index algorithm, you can also create FullText indexes using the Lucene Engine. By data store, we mean something that stores documents filled with information. The correct name for the process of finding right information from data store is information retrieval. Search engine is a piece of software that helps users find the most relevant documents from a big document collection (data store) in a simple and performant manner.Using them is very straightforward: A .LucenePDFConfiguration instance is created.īuilding a search engine (Lucene tutorial) - Medium Weblucene-pdf enables Lucene indexing of PDF documents with two classes: .LucenePDFDocumentFactory and .LucenePDFConfiguration.

Sitefinity does not index the contents of. The documents in the following formats are supported for indexing: - TXT - HTML - RTF - DOCX (Office Open XML – the binary DOC format is not supported) - PDF.The Lucene query language allows the user to specify which field(s) to search on, which fields to give more weight to (boosting), the ability to perform boolean queries (AND, OR, NOT) and other functionality.What types of documents are supported for indexing? Lucene has its own mini-language for performing searches. It involves creating a Query (usually via a QueryParser) and handing this Query to an IndexSearcher, which returns a list of Hits. Searching requires an index to have already been built. Indexing in Lucene thus involves creating Documents comprising of one or more Fields, and adding these Documents to an IndexWriter. In the case of a title Field, the field name is title and the value is the title of that content item. For example, a Field commonly found in applications is title. For example, if you're creating a Lucene index of a database table of users, then each user would be represented in the index as a Lucene Document.Ī Document consists of one or more Fields. Indexing involves adding Documents to an IndexWriter, and searching involves retrieving Documents from an index via an IndexSearcher.Ī Lucene Document doesn't necessarily have to be a document in the common English usage of the word. In Lucene, a Document is the unit of search and index.Īn index consists of one or more Documents. This type of index is called an inverted index, because it inverts a page-centric data structure (page->words) to a keyword-centric data structure (word->pages). This would be the equivalent of retrieving pages in a book related to a keyword by searching the index at the back of a book, as opposed to searching the words in each page of the book. Lucene is able to achieve fast search responses because, instead of searching the text directly, it searches an index instead. The content you add to Lucene can be from various sources, like a SQL/NoSQL database, a filesystem, or even from websites. It then allows you to perform queries on this index, returning results ranked by either the relevance to the query or sorted by an arbitrary field such as a document's last modified date. It does so by adding content to a full-text index. Lucene is a full-text search library in Java which makes it easy to add search functionality to an application or website.
