Shay Banon, creator of Elasticsearch, kicked off...Continue reading

Talks: Replacing Autonomy IDOL with Solr, Elasticsearch for e-commerce & relevancy tuning

I'll be speaking at several events over the next few weeks, in the UK and abroad. On the 19th of November I'll be at the FIBEP World Media Intelligence Congress in Vienna, to talk about how we helped our client Infomedia migrate from a closed-source search engine (Autonomy IDOL and Verity) to a new platform based on Apache Lucene/Solr<...Continue reading

Why building an open source search team is hard – and how we can help

A common complaint from our clients is how difficult it is to find staff with experience of search applications and in particular Apache Lucene/Solr or Elasticsearch. With the explosive growth of open source search over the last few years, there simply aren't enough people on the market with the right skills and...Continue reading

Elasticsearch Meetup – Spark, postcodes and Couchbase

Three speakers for this month's Elasticsearch Meetup (slides now up), kindly hosted by JustEat's technical department. Neil Andrassy kicked us off with a talk about how TheFilter (which you may know counts Peter Gabriel as an investor) use Apache Spark to ...Continue reading

London Lucene/Solr Usergroup – website search and indexing the cloud

This week's London Lucene/Solr Meetup was hosted by asset management company BlackRock who also provided our first speakers. BlackRock manages an astonishing $4.7 trillion in assets (that's more than the GDP of Germany) and operates 90 different websites with around 250,000 content items, so a good and accurate website search engine is essenti...Continue reading

In early September we're running another free to attend London Lucene/Solr Usergroup Meetup, sponsored this time by Blackrock who are talking about using Solr for websites. At the end of Septem...Continue reading

Elasticsearch Percolator & Luwak: a performance comparison of streamed search implementations

Most search applications work by indexing a relatively stable collection of documents and then allowing users to perform ad-hoc searches to retrieve relevant documents. However, in some cases it is useful to turn this model on its head, and match individual documents against a collection of saved queries. I shall refer to this model as "streamed search". One example of streamed search is in media monitoring. The monitoring agency's ...Continue reading

BioSolr at BOSC 2015 – open source search for bioinformatics

Matt Pearce writes: I spent most of last Friday at the Bioinformatics Open Source Conference (BOSC) Special Interest Group meeting in Dublin, as part of this year's ISMB/ECCB conference. Tony Burdett from EMBL-EBI was giving a quick talk about the BioSolrContinue reading

The four types of open source search project

As I'm currently writing content for our new Flax website (which is taking far longer than anticipated for various reasons I won't bore you with) I've been thinking about the sort of projects we encounter at Flax. You might find this useful if you're planning or starting a search project with Solr or Elasticsearch. Note that not everything we do fits cleanly into these four categories! Continue reading

Innovations in Knowledge Organisation, Singapore: a review

I'm just back from Singapore: my first visit to this amazing, dynamic and everchanging city-state, at the kind invitation of Patrick Lambe, to speak at the first Innovations in Knowledge Organisation conference. I think this was probably one of the best organised and most interesting events I've attended in the last few years. The event started with an enthusiastic ...Continue reading
