Better performance with the Logstash DNS filter

We've been working on a project for a customer which uses Logstash to read messages from Kafka and write them to Elasticsearch. It also parses the messages into fields, and depending on the content type does DNS lookups (both forward and reverse.) While performance testing I noticed that adding caching to the Logstash DNS filter actually reduced performance, contrary to expectations. With four filter worker threads, and the following configuration: 
dns { 
  resolve => [ ...

So I'm thus very happy to announce we'll be involved in three Lucene hackday events over the next two months: Firstly, Read more

Boosts Considered Harmful – adventures with badly configured search

During a recent client visit we encountered a common problem in search - over-application of 'boosts', which can be used to weight the influence of matches in one particular field. For example, you might sensibly use this to make results that match a query on their title field come higher in search results. However in this case we saw huge boost values used (numbers in the hundreds) which were probably swamping everything else - and it wasn't at all clear where the values had come from, be it ex...

Quepid is an innovative tool from our partners Open Source Connections, which allows you to bridge the gap between content owners (who really know what's in your search index and how people might search for it) and search developers (who can tweak the search engine to improve relevance, given some examples of 'good' and 'bad' results for a query). We're increasingly using it in...
