For example, when indexing traditional files such as Word, HTML, and PDF documents, commonly used fields are вЂњtitleвЂќ, вЂњbodyвЂќ, вЂњkeywordsвЂќ, вЂњauthorвЂќ, and вЂњlast_modified_dateвЂќ. Fields are the useful individually named attributes of a document used by your search application. Lucene provides APIs to open, read, write, and search an index. In other words, when thinking Lucene, it is important to consider the use cases / demands of the encompassing application in order to effectively tune the indexing process with the end goal in mind. Documents are вЂњindexedвЂќ.Дocuments are a representation of whatever types of вЂњobjectsвЂќ and granularities your application needs to work with on the search/discovery side of the equation. The design of Lucene is, at a high level, quite straightforward. Lucene Java and Core Lucene Concepts Explained This is a commonly used factor, computing the relationship between term frequency (how many uses of the query term exists in the entire index) to the inverse document frequency (how many documents in the entire collection that contain that query term, inverted). Term frequency / inverse document frequency. Searchable text, extracted from each indexed field by analysis (a process of tokenization and filtering).

Other common fields are вЂњtitleвЂќ, вЂњbodyвЂќ, вЂњlast_modified_dateвЂќ, and вЂњcategoriesвЂќ. Documents typically have a unique key field, often called вЂњidвЂќ. Property, metadata item, or attribute of a document. A document typically represents a crawled web page, a file system file, or a row from a database query. There are many common terms used when elaborating on LuceneвЂ™s design and usage.

LucidWorks Enterprise is Lucene and Solr, plus more. If youвЂ™re getting started on building a search application, your quickest, easiest bet is to use LucidWorks Enterprise.

Apache Solr вЂ“ a great starting point for developers grab a distro, write a script, integrate into UI.

LucidWorks for Solr вЂ“ certified distributions of the official Apache Solr distributions, including any critical bug fixes and key performance enhancements.

We recommend you start with one of the following distributions: Solr provides some very direct ways to interact with Lucene. WeвЂ™ll be shining the light on Lucene internals and concepts with Solr. This Refcard is about the concepts of Lucene more than the specifics of the Lucene API. Solr factors in Lucene best practices and simplifies many aspects of indexing content and integrating search into your application as well as addressing scalability needs that exceed the capacity of single machines. Apache Solr, specifically, is a top notch server architecture, built from the ground up with Lucene. However, some better and easier ways to build Lucene-based search applications are now available. If youвЂ™ve got Java skills you can easily grab lucene.jar and go for it. Lucene has only gotten better since then: faster, more efficient, newer features, and more.

It served its purpose and did so extremely well. When Lucene in Action was published in 2004, before the advent of many of the projects mentioned above, we just had Lucene Java and some other open-source building blocks. How you choose to go about it will depend on your specific needs and integration points, your technical expertise and resources, and budget/time constraints. There are many ways to obtain and leverage Lucene technology. There are many projects and products that use, expose, port, or in some way wrap various pieces of the Apache Lucene ecosystem. Adds faceting, replication, sharding, and more.ДЄims to collect and distribute free materials for relevance testing and performance. High-performance enterprise search server. Also comes with extras such as highlighting, spellchecking, etc. The following table shows the key projects at. The name is also used for various ports of the Java library to other languages (Lucene.Net, PyLucene, etc).

Lucene was then chosen as a top-level Apache Software Foundation project name. ItвЂ™s the original Java indexing and search library created by Doug Cutting.
