Migrating Apache Solr to Elasticsearch
Elasticsearch is the innovative and advanced open source distributed search engine, based on Apache Lucene. Over the past several years, at Trifork we have been doing a lot of search implementations. Driven by the fact that every other customer wanted the ‘Google-experience’ (just a text box, type some text and get relevant results) as part […]
There’s More Lucene in Solr than You Think!
We’ve been providing Lucene & Solr consultancy and training services for quite a few years now and it’s always interesting to see how these two technologies are perceived by different companies and their technical people. More precisely, I find it interesting how little Solr users know about Lucene and more so, how unaware they are […]
Apache Lucene FlexibleScoring with IndexDocValues
During GoogleSummerOfCode 2011 David Nemeskey, PhD student, proposed to improve Lucene’s scoring architecture and implement some state-of-the-art ranking models with the new framework. Prior to this and in all Lucene versions released so far the Vector-Space Model was tightly bound into Lucene. If you found yourself in a situation where another scoring model worked better for your […]

Gimme all resources you have – I can use them!
Exploiting full IO and CPU concurrency when indexing with Apache Lucene During the last year Apache Lucene has been improved an extreme amount with outstanding improvements such as 100 times faster FuzzyQueries, new Term-Dictionary implementation, enhanced Segment-Merging and the famous Flexible-Indexing API. Recently I started working on another fundamental change referred to as DocumentsWriterPerThread, an […]
