In 2011 we launched SearchWorkings.org, a community website that aimed to bring search professionals together, mostly around open source search technologies like Apache Lucene and Apache Solr. At the time, the number of resources providing high value content around those technologies was limited. Therefore, we created the searchworkings portal, providing blog entries, white papers and […]
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 […]
Summer time…
For those you may have missed our newsletter last week I’d like to take this opportunity to give you a quick lowdown of what we’ve been up to. The summer months have been far from quiet and I’m pretty excited to share in this month’s edition lots of news on projects, products & upcoming events. […]
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 […]
Query time joining in Lucene
Recently query time joining has been added to the Lucene join module in the Lucene svn trunk. The query time joining will be included in the Lucene 4.0 release and there is a possibility that it will also be included in Lucene 3.6. Lets say we have articles and comments. With the query time join […]
Berlin Buzzwords 2012
Yes, Berlin Buzzwords is back on the 4th & 5th June 2012! This really is only conference for developers and users of open source software projects, focusing on the issues of scalable search, data-analysis in the cloud and NoSQL-databases. All the talks and presentations are specific to three tags; “search”, “store” and “scale”. Looking back […]
The Lucene Sandbox
Few people are aware that Apache Lucene has been part of the ASF since 2001, becoming a Top Level Project in 2005. 10 years is an eternity in IT where ideas tend to evolve in leaps and bounds. Over that 10 year period many users, contributors and committers have come and gone from Lucene, each […]
Hotspotting Lucene With Query Specialization
Most Java developers probably take the technology behind HotspotTM for granted and assume it’s best suited to optimize their code. While they might know that choosing the best implementation of List will have a big impact on their program’s performance, they probably shy away from worrying about the cost of virtual method calls, believing Hotspot […]
Lucene indexing gains concurrency
Imagine you are a Kindergarten teacher and a whole bunch of kids are playing with lego. Suddenly it’s almost 4pm and the big mess needs to be cleaned up, so you ask each kid to pick up one lego brick and put it in your hands. They all run around, bringing bricks to you one […]
SSP 2.0 – Spatial Search Plugin for Solr
It has been over a year since we released our Spatial Solr Plugin (SSP) to the community and its great to see that its serving so many users so well. During that time there has also been a great deal of work done on adding official spatial search support to Solr. Much of this work is now […]
