Can Lucene be used as database?
Can Lucene be used as database?
Lucene is not a database — as I mentioned earlier, it’s just a Java library.
How is Lucene implemented?

What is Lucene based search?
Essentially Apache Lucene is a full-text search engine software library that provides a Java-based search and indexing platform. Using Java it lets you add search capabilities to websites or applications. It takes content and adds it to a full-text index which can then be used to perform queries.
Why Lucene is so fast?
Why is Lucene faster? Lucene is very fast at searching for data because of its inverted index technique. Normally, datasources structure the data as an object or record, which in turn have fields and values.
Where is the Lucene index stored?
When using the default Sitefinity CMS search service (Lucene), the search index definition (configurations which content to be indexed) is stored in your website database, and the actual search index files – on the file system. By default, the search index files are in the ~/App_Data/Sitefinity/Search/ folder.
How do you make Lucene index in AEM?

- Name the node LuceneIndex and set the node type to oak:QueryIndexDefinition.
- Add the following properties to the node: type: lucene (of type String)
- Save the changes.
What is Lucene used for?

Does Lucene support crawling and HTML parsing?
Lucene itself is just an indexing and search library and does not contain crawling and HTML parsing functionality. However, several projects extend Lucene’s capability: Kinosearch – a search engine written in Perl and C and a loose port of Lucene. The Socialtext wiki software uses this search engine, and so does the MojoMojo wiki.
Is Lucene supported by the Apache Software Foundation?
