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

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

The four types of open source search project

His first talk was on Search Relevancy, an area that we often deal with at Flax: how to tune a search engine to give results that our clients deem relevant, without affecting the results for other queries. Using a ...Continue reading
