In Lucene 4.x there is an API to fetch index statistics for specific document’s fields.

The following examples shows how to create an index with some random documents and fetch some statistics for a field afterwards ..

Lucene Dependencies

Just one dependency needed here .. lucene-core. I’ve added the declarations needed for Maven and SBT here .. if you’re using Gradle or Buildr you should’t have a problem to create your build file either..

Extending the Confluence Search Index

Sun, 23 May 2010 00:00:00 +0200

Developing plugins for the Confluence Wiki a developer sometimes needs to save additional metadata to a page object using Bandana or the ContentPropertyManager. Wouldn’t it be nice if this metadata was available in the built-in Lucene index?

That is were the Confluence Extractor Module comes into play..

Overview

An extractor allows the developer to add new fields to the lucene search index. Creating a new extractor is quite simple – just implement the interface com.atlassian.bonnie.search.Extractor or bucket.search.lucene.extractor.BaseAttachmentContentExtractor if you want to build a new file extractor.
